Update a field based on whether a button is checked or not

I have this form that needs to do the following

When the checkbox named "Assigned" is checked I need the field "ContolTNum " to be assigned the value from a second form named Forms!frm1POSControlTicket!ControlTicketNum. When the button is unchecked the field should be null

currently the code I have is as follows

Private Sub Assigned_Click()
Me.Refresh
Forms!frm_qry_tbl_visa_imports!ContolTNum = Forms!frm1POSControlTicket!ControlTicketNum

End Sub

Open in new window


Obviously as you can guess everytime i check or uncheck the box, the field updates to the set value. I do need to add some logic that when the button is unchecked to convert the field back to null (not assign a value to the field.

thanks

Try this:

Private Sub Assigned_Click()
Me.Refresh
If Me.Assigned = true then
    Forms!frm_qry_tbl_visa_imports!ContolTNum = Forms!frm1POSControlTicket!ControlTicketNum
Else
    Forms!frm_qry_tbl_visa_imports!ContolTNum = Null
End if 
End Sub

Also - I think I mentioned this in another question - you do not need the full form reference if the code is on the same form:

Try this if the code is on frm_qry_tbl_visa_imports:

Private Sub Assigned_Click()
Me.Refresh
If Me.Assigned = true then
    Me.ContolTNum = Forms!frm1POSControlTicket!ControlTicketNum
Else
    Me.ContolTNum = Null
End if 
End Sub

Open in new window


Or this if it is on frm1POSControlTicket:

Private Sub Assigned_Click()
Me.Refresh
If Me.Assigned = true then
    Forms!frm_qry_tbl_visa_imports.ContolTNum = Me.ControlTicketNum
Else
    Forms!frm_qry_tbl_visa_imports.ContolTNum = Null
End if 
End Sub
