Only show formula results if not 0 (zero)

I currently have a formula set to look at cell A2 and provide Friday's Date in cell B2 if Monday through Friday.

For Example:

Mon 10/27/2008 then formula result is 10/31/2008
Tuesday 10/28/2008 then formula result is 10/31/2008....etc.

Below is the formula I am using.

=IF(WEEKDAY(D2,1)>=6,D2+((6-WEEKDAY(D2,1)))+6,D2+((6-WEEKDAY(D2,1))))

I only want the formula result to display if the result is NOT equal to 0 (zero). So if there is no date in A2 then the B2 would be a blank cell with no formula results. Currently the result of the formula in B2 if A2 is blank is 1/5/1900 (Date Format)

Any help would be greatly appreciated.
