After posting my original request, I realized that I haddn't given much information.

I assumed that since IB Expert listed all the functions, that they had been declared. I don't know if that is a safe assumption.

Helen, I'm not sure if *in the database* means in the Stored Procedure, or elsewhere. I'll follow your suggestion and look up DECLARE EXTERNAL FUNCTION. Thanks for the quick reply.

Oh, BTW, I've tried several other functions that are visible in the UDF list, and all of them gave the same "entry point" error.
