I am able to input bar code scans into Cell A1 into a chemical inventory spread sheet. In column B1 I used the =MATCH function to return the row it is found in. I now need to have a text character , say an "X" returned into the last column (G) of my spread sheet after each row entry and for the X to stay in the cell when I go to scan the next chemical's bar code. Items which have not been found can remain blank and then removed from inventory. Thank you for any input.
