Hey all,
I've been having some help here with my spreadsheet (not to good with Excel) and once again have come across another problem I can't work out or find a solution for.
In A1 there is a number and I want this number to go down by whatever number is entered into cells C3 - C20
Just to clarify, if I add 5 to C3 (making it 20), A1 will change to 495, if I then add 20 to C13, A1 will change to 475 etc.
Could someone explain how this is done please?
Thank you

You can't enter a number into a cell, then consecutively subtract from it with formulas (only with VBA)
To avoid VBA, enter the 500 in another cell (except within column C), say B1 (you can hide it by colouring the font to match the background).
Then in A1 enter formula: =B1-SUM(C:C)

Use this formula in A1 -=500-SUM(C3:C20)
