>Hi Cetin,
>Sorry about that, I thought you were asking if I was using Iif in the expression for the sum of the horizontal records. I used the .null. and it worked! Thanks! Is there a way to prevent the .null. from showing up on the report? Thanks again!

Set nulldisplay to ''

Or yupu could set it to something else :
Set nulldisplay to 'Unknown'
