Updating quanity of inventory automaticly

[Guest]

I am the manager of a small warehouse and am using a access database that a
former colleage wrote to track inventory. I would like to modify what he has
written to be able to modify the inventory count by typing into a field and
having the database do the math for me. The current setup has the inventory
count unlocked so that I manually do the addition or subtraction then type in
the new inventory count. While not completely computer illiterate, i have
very little history with database systems and trying on my own just ended up
in a backup restore. Im sure that it has to be possible but I have no idea
how. I would appreciate any tips or advice on where to start. Thank you.

What are you typing into the "field" (Not really a field because forms have
controls, tables have fields)?
What controls on the forms are involved?
What is the math?

Actually, in looking around a bit to make sure i knew how to answer your
question without sounding like a clueless idiot I found exactly what I needed
to figure it out on my own. Its not elegent or pretty but it works. Soooo,
really without even saying anything you helped me more you appreciate. Thanks

Great!
Sometimes it just takes a fresh idea to point you in the right direction.
