I am doing a project at work where my boss want a spread sheet set up with an on screen search feature. To search PO's, part numbers etc. I thought no problem, I simply used VLOOKUP on the sheet, entered the information he wanted and I am thinking i am done. But NO, he wants it to start searching as soon as he types in a PO or part number. So say there are 100 part numbers that start with "4". He wants it to start showing "possibilities" as soon as he types in the 4, then it starts narrowing down to the exact number. Not sure I am explaining it clear enough. I know exactly what he is wanting. I just dont know what it is called, or find any code online to do it with. Anyone got any ideas?
