Bit stuck here wondered if anyone can help? Is this possible?

I'm trying to create a sheet to record the movement of stock. I have
large number of stock items listed by name in one column. What I'd lik
to do is a have a single cell at the top where I enter the name of a
item and a commulative count will appear next to that item on the list
After entering the name it can be deleted from the single cell at th
top  and the next name entered, and so on. Is this possible? Am I goin
to have to stray into the world of macros? Please help as my brain i
melting :eek:
