Suppressing a text field based on date range

[AMills]

I'm trying to suppress a text field when the date of a data field is less than or equal to 7/1/11. Can anyone give some tips? I right clicked on the text box, went to format field, and then clicked the formula box next to "Suppress" I started with:
if {data field} <= #7/1/11# then
and there's my problem.. I don't know what to put next to suppress the box

I found a solution to my problem. I was making this overly complicated. I deleted the text box and just made a formula that added the text I needed if my criteria was met.

However the answer is: if {data field} <= #7/1/11# then True
