In the new form I initially 'seemed to have' fixed the problem by capturing me.openargs value into a variable in the FormOpen event. Now, that is passing as Null. I've tried structuring the calling code directly using me.Name, tried it by setting a string variable to me.Name's value then passing that, even tried various combinations. Oct 27, 2010 OK, so here is the problem. If you had the report open in Design View, you cannot reference the OpenArgs. The report has to be completely closed, and then opened via the form for this to work. Strange, but true. I guess it's just one of those MS Access 'things'. Passing a Value to a Microsoft Access Form or Report with its OpenArgs Parameter. The OpenArgs parameter is one of the values you can pass to a form or report when you open it with the DoCmd command. Rather than creating global variables, assigning them and having the form/report use it, passing the information through the OpenArgs parameter. Apr 25, 2017 If you really want to pass value to independent form, the OpenArgs is a good approach. Probably need to open the form to a new record row. DoCmd.OpenForm 'InvoiceItem', acFormAdd, acDialog, Me!InvoiceNumber. Need code that makes sure the form is on a new record.

Passing a Value to a Microsoft Access Form or Report with its OpenArgs Parameter
The OpenArgs parameter is one of the values you can pass to a form or report when you open it with the DoCmd command. Rather than creating global variables, assigning them and having the form/report use it, passing the information through the OpenArgs parameter makes your code cleaner and easier to support and understand. Global variables can quickly get confusing if they are assigned in multiple places.
Here's the complete definition of the OpenForm command from the Microsoft Access Help system:
DoCmd.OpenForm FormName, View, FilterName, WhereCondition, DataMode, WindowMode, OpenArgs
Parameter Definitions
| Name | Required? | Data Type | Description |
|---|---|---|---|
| FormName | Yes | Variant | A string expression that's the valid name of a form in the current database. If you execute Visual Basic code containing the OpenForm method in a library database, Microsoft Access looks for the form with this name first in the library database, then in the current database. |
| View | No | AcFormView | The AcFormView constant specifies the view in which the form will open. The default value is acNormal. |
| FilterName | No | Variant | A string expression that's the valid name of a query in the current database. |
| WhereCondition | No | Variant | A string expression that's a valid SQL WHERE clause without the word WHERE. |
| DataMode | No | AcFormOpenDataMode | A AcFormOpenDataMode constant that specifies the data entry mode for the form. This applies only to forms opened in Form view or Datasheet view. The default value is acFormPropertySettings. |
| WindowMode | No | AcWindowMode | A AcWindowMode constant that specifies the window mode in which the form opens. The default value is acWindowNormal. |
| OpenArgs | No | Variant | A string expression. This expression is used to set the form's OpenArgs property. This setting can then be used by code in a form module, such as the Open event procedure. The OpenArgs property can also be referred to in macros and expressions. For example, suppose that the form you open is a continuous-form list of clients. If you want the focus to move to a specific client record when the form opens, you can specify the client name with the openargs argument, and then use the FindRecord method to move the focus to the record for the client with the specified name. |
The DoCmd.OpenReport command has similar parameters.
Unfortunately, it's not possible to pass multiple OpenArgs parameters to a Microsoft Access form or report, or pass an array of values. Only one OpenArgs string can be used in the OpenForm or OpenReport command.
By combining your values into one string separated by a character that would not be in your string, you can overcome the OpenArgs limitation and still use DoCmd to pass them. The OpenArgs parameter is a string that the form can read once it is opened. Calling the form, add the string to the OpenArgs parameter like this:
Similarly, for reports, you can use this:

A real-life example would be to set default values for controls on a form being opened. Suppose that you have a form of Product Categories, and the user needs to enter a new product for the category. You could open the Product entry form and then default the category value for them. With the following parameter, you could default the Category combo box to the current value.
For example:

which may result in a value such as 'cboCategory|123'
Rather than explicitly specifying the parameter, you can also pass it as the last parameter in the list:

In the Load event of the Form, add some VBA code to parse the information that is being passed in OpenArgs. In this example, we are using two values, separated by the 'Pipe' (|) character. The code in the form finds the existence of the Pipe character, then extract the first and second values to make the assignment.
