Are you referring to the red flow arrow? I guess this is the visual indication of an "Inconsistent Flow" warning (repetitive source to non-repetitive target) which in itself is not a real problem since you are probably searching by User_id, which means Find will always return at most one record.
Your screenshot is is not clear so I can't be sure, but it looks like Find itself is repetitive which makes no sense (as there will be only one input coming from the non-repetitive Lower Case).
To resolve the issue you're actually dealing with, which is not clear to me, I suggest you acquaint yourself with the visual debugging (Trace) functionality - see http://www.tersus.com/#Id=46.
