the formula
=IF(C3<>"",IF(ISERROR(VLOOKUP(C3,‘Item List’.A:Z,2,0)),“New Item”,VLOOKUP(C3,‘Item List’.A:Z,2,0)),"")
causes a lockup unless there is not an “Item List” tab, or that tab is empty. With any information in the “Item List” tab, even one cell, opening Function Wizard takes a long time and if there is quite a bit of information, it locks up completely.
C3 is a bar code and “Item List” is a large database of bar coded items.
