Hey all, this may seem abit silly but im having real trouble working out how to make a php form that subtracts and adds numbers from 3 different box's into a new box..
abit like this...
box 1:
10
box 2 adds:
1
box 3 minus:
5
Result:
6
im guessing its really simple but im extremely tired and ive been at it for about 3 hours :(
might cry
someone help?
