Be specific first.

What function is undefined?

===============================================================

No problem. I ran select * from name account where left (name _ code, 1) = 1 in ACCESS and got the correct result. It shouldn't be the problem here, or you put the left ([student]! [Student ID], 4) changed to the left (Student ID, 4)
