So, I have a simple(or so I thought) formula to weed out only records I want.
It looks like this:

{T_Success.zenDateTime} in {?start_date} to {?end_date}
and
InStr ({T_Success.zenAppTDN},"ADOBE",1 )>1

The report works with the first set of logic(the date range),but
I added the second bit of logic this morning, to return only those columns bearing the string "ADOBE".

I now get no returns, though I know there's data with "ADOBE" present.
The column data contains the string  "ADOBE" plus a lot of other text as well.

Thanks..
Rich

ok, thanks much for confirming the logic is good.

I see yer point..
