Can you open the database and all tables involved in advance?

But anyway, since you're using UDF in Select statement, it may behave unpredictably.

You may still want to post the exact select + UDF code, so we can help figuring out what's wrong.

Otherwise you may leave the working 70 solution, perhaps it's not worth the trouble.
