    No problem.  First set the field properties for the numeric field [num] to uncheck "treat blank as zero".

    then use the formula

    IF(IsNull([num]), false,true)

    This always bites me! I asked this question months ago and still haven't learned my lesson. I appreciate finding this post to lead me back to that lousy check box!
