Hi All, I posted this message below a couple of weeks ago but because of work commitments I was unable to repond to any o the replies I had and my post was closed, So I have copied my origninal post below in hope that I get solve my problem this time.
Hi all,
I have created a basic stock list speadsheet that appeared to work at first using the countif statement, but have found one major flaw in it, If I check an item of stock out and then check it back in then that item of stock is counted twice and my total stok count is incorrect (over by 1),
I think I need to use a little bit of a database in my spreadsheet but have never done it before, How can I go about making my spreadsheet count an item only once regardless of how many times I check it in or out, so that I can get a true stock count when needed.
Background to my stock - basically i get a shipment of PC's for one customer that I store in a holding cage, I need to have an accurate count of the PC's at all times. I will take a PC out of the holding cage and work on it, then I return it to the cage (so the stock of the cage goes down by one and then back up by one) this is all tracked by the PC serial number, When appropriate I will take a certain number of machines out of the stock and install them at a site, but again I need to make sure that the total number of PC's (in my holding cage, in my warehouse and out on site) matches my original delivery count.
I have attached a copy of the spreadsheet that I am using, Basically I have been scanning in the serial numbers into the Stock in Sheet and then Scanning them out on the Stock out sheet, you will see what I have tried to explain above when you look at it. Someone did mention that I could use an indicator to show whether or not an item is in or out but I didn't really understand what they meant
Thanks in advance
