Runtime error 2498 - Wrong data type

[jalbright1957]

I have a navigation form with (3) subforms within (1) tab. The customer table in this particular instance is the parent to the customer contacts table. Customer form is a single form, contacts form is a continuous form. Customer table has the PK CompanyID, customer contacts table has the PK ContactID and the FK CustomerID.

In the footer of the customer contact form there is a button to enter a new contact and selecting it opens a separate form to input a new customer contact. When doing this I get the error "Runtime error 2498 Expression entered is the wrong data type for one of the arguments".

Below is the Click event to add a contact and the On Load event of the form it is supposed to load:

Private Sub btnAddContact_Click()
DoCmd.OpenForm "frmAddCompanyContact", , , , acFormAdd, , Me!CompanyID
End Sub

Private Sub Form_Load()
  If Not IsNull(Me.OpenArgs) And Me.NewRecord Then
      Me!CompanyID = Me.OpenArgs
  End If
End Sub

OpenArgs are strings - ie text values. If CompanyID is a numeric value (as I suspect), you need to convert it in your form_load event to the suitable format.

I neglected to check what the data type arguments are supposed to be when using openargs and didn't realize it required a text value. Since I'm using the PK (numeric), obviously this wouldn't work. I would rather not go through data conversions so on to a different method. I'm still green with Access and have to look up most methods. Have a better method you can recommend?
