Hi there,
Thanks for your reply. I've literally just set up the calculation with Sum in it, and it appeared to fix the problem of only adding the current page. However i have had the issue of restocking the supplies, and im trying to decide a suitable, and simple solution at the moment.
The idea of a restock table works, but over time, and this database could be used for many years, some items would end up with about 300 repititions.
I quite liked the idea of having a button that can 'Add' 'x' amount to the current stock, but i cant seem to find a way to do this. For example;
Current stock 101. Button = Add (x) amount.
Clicking the button takes the typed amount and adds it to current stock. That can work find but it seems each time i change the amount, the Current stock level deducts the previous added amount before adding the new.
For instance, current stock = 100. I add 10 which = 110. Next update i type 20 into the add 'x' box, but the calculation appears to minus the 10 before adding the 20. It doesnt accumulate. Any easy way around this? Thanks again, and i apologise if that didn't make a great deal of sense.
