Return Blank Cel Instead of the word FALSE

[islandeeya]

Hello,

I need a blank cell instead of a "FALSE". here's my formula:

=IF(A1>=7/31/8,IF(B1="y",A1)," ") (basically, if the date in A1 is equal or greater than 7/31/08, and if B1 is "yes" then enter info from from A1) (A is a date if that matters)
Thank you...
