Well, when I tested the code, It was still allowing 2 requests to update/read the table at the same time. It may only be in the case tha tI am facing when I am updating the table but also need to output the new value that was updated. I may just be attacking this problem wrong too.

Sorry for seeming a bit dense, but what's the problem with using "LOCL TABLES" for all SQL stmnts? It's my understanding that it will lock tables and prevent other procs from reading/writing to that table while you've got a lock on it.
