Use Popup Form To Select A Record On The Main Form

Can anyone see what I am doing wrong?

I have a main form that has a tab control on it. The main form is called frm_AddNewCompanyContacts. It is opened in edit mode. To see if a company exists I use a command button to call a popup form with a list of all companies' IDs and names. I then want the user to be able to click on a commad button on the popup form to take the main form to that record. After an intial post, and subsequent search, I found the appropriate code. This is what I am using for the onclick event of the command button on the popup form:

Private Sub cmdGoToCompany_Click()
Dim rst As Recordset
Set rst = Forms![frm_AddNewCompanyContacts].RecordsetClone
rst.FindFirst "[CompanyID]='" & Me![CompanyID] & "'"
If rst.NoMatch = False Then
Forms![frm_AddNewCompanyContacts].Bookmark = rst.Bookmark
End If

End Sub

When I click on the command button I get an error message:

"The expression On Click you entered as the even property setting produced the following error: A problem occurred while Microsoft Office Access was communication with OLE server or ActiveX Control (I don't have an ActiveX Control).

*The expression may not result in the name of a macro, the name of a user-defined function, or [Even Procedure].
*There may have ben an error evaluating the function, event or macro."
