I am using INDEXSEEK in the stored proc. of my DB to check on the validity of the primary key that I am about to assign. The call is as follows:

IF INDEXSEEK(m.cKey, .f., m.cTable, "PKey")

Works great on my machine, whether from within VFP6 or via the EXE file of the app. On site, however, whenever it is invoked, the error message "Cannot find file INDEXSEEK.PRG" (or words to that effect) pops up. I had the client check the \WINDOWS\SYSTEM folder--the VFP6 DLL's are in place. Any ideas out there as to what might be going on??

TIA.
