To make a Subform Object visible/not visible you don't need .Form.
You can just say SubformName.Visible = False.

Hi Marc
I just made a small demo for you. My question is - If you use a table with an autonumber you will never have a null. What do you have for data in your combo box?

John

The Combo Box could have a Null value if there is no item selected or it has been cleared.

Thanks John, the combo was set up using the wizard with column 0 as PK Autonumber and Description Column 2. I then removed the control source to make it unbound. Attached screenshot. Kevins right, the null is to capture when the Combo is unselected or has been cleared. I don't want either subform to display until the user decides which route to take and selects the option from the combo. If they change their mind then i need the form to switch to the other choice. I corrected the If statements to SubformName.Visible = False but still cannot get it to behave as required. Again i fiddled and fiddled with the statement. Do you guys think that a loop is required? I have only looped once before and Scott helped me with code. It was by a while loop on a recordset but with this particuar scenario i don't see how i can use a recordset as its unbound and im only trying to display forms.
