Oops, I didn't realize I was doing C style comparison operators.

OK, I changed that. It now looks like

[&EXPANDSUM(PART;stores_PART_tries==1?6:(stores_PART_tries==2?2:(stores_PART_tries==3?-4:-12)))]


and still gives the traditional undefined value.

It seems like whenever I try and access "tries" things mess up.
Does the EXPANDSUM look at part 0 (stores_0_tries)? Since this is blank, I
am wondering if that messes up the construct.

Or, maybe the negative signs are a problem?

Thanks,
brew

Try this:
 [&EXPANDSUM(PART;stores_PART_tries==1?6:(stores_PART_tries==2?2:(stores_PART_tries==3?0:-2)))]

( '=' is assignment, '==' is numerical comparison, 'eq' is text comparison
)
