The following example opens the frmMainEmployees form in Form view and displays only records that apply to the department chosen in the cboDept combo box. The displayed records can be edited, and new records can be added.Sample code provided by: Bill Jelen, MrExcel.com
Code:
VBCopy
Private Sub cmdFilter_Click()
DoCmd.OpenForm "frmMainEmployees", , , "DepartmentID=" & cboDept.Value EndSub
Guess I could use this? Just how do I select the main form which contains the combobox? VBA is still foreign for me 
Code:
VBCopy
Private Sub cmdFilter_Click()
DoCmd.OpenForm "frmEmployees", , , "CompanyID=" & "AllForms!frmMain" Me. cmb.cboCompanyID.Value EndSub
Any close? lol
And thanks for the help, would search forever
