Hi: When I use the absolute column reference it is ALWAYS _C2_, _C3_, _C4_, etc...you need those underscores. And, the good news is that because it is the ABSOLUTE column number, you don't need the .sum as you would with a "regular" numeric item. So you should be able to simplify your formula to something like: PCTUTD = _C5_ / _C4_; Without data it's hard to guess. I thought I showed using OUT= in the paper to be able to understand which column numbers belonged to which column so you could get the numbers right. But, also remember, if PCTUTD is UNDER TYPE, then if you have 2 types, you'll also get absolute column numbers for two values for PCTUTD under each TYPE as well. Something like this -- these columns are totally made up, because I don't quite understand your COLUMN statement without data to run through the program to double check. _C6_ = _C5_ / _C4_; _C8_ = _C7_/_C4_; I see that you're using UTD in Part 2 and I see UTD in a DEFINE in Part 3, but why isn't UTD on the COLUMN statement in Part 3? You'll probably get an error without UTD in the COLUMN statement and if you use PCTUTD under TYPE and not under TYPE, then you'll have a problem too with the COMPUTE block. Also, when you calculate PCTUTD under each value of TYPE, don't you also need the TOTALCHILDREN value for each TYPE so the division works out. I can't figure out from your posted data example, what the right numbers should be. Can you mock up something with the actual numbers that you expect to get based on the data you posted? Because otherwise, it's very hard to understand what is getting divided by what to produce PCTUTD. Also, I'd recommend ditching the final COMPUTE block for ALL right now and concentrate on getting the overall column header structure and numbers right every place else and then do the COMPUTE block for ALL because you don't want to fiddle with it while you're getting everything else just right.
