Hi Help needed, with the rising costs of Energy Bills, I am trying to keep a record of usage.

Low and behold I have come my first obstacle. I keep getting the meter reading coming up as a Negative  figure in the next column. The formula used is =D3-C3 then filled along. If I put in a new formula each week then all is OK. Will stick a picture below. (not the actual readings just testing)

Probably 1 of many questions.

Thanks for help in advance.

You could change the formula in D5 to =IF(D3=0,"",D3-C3) and fill to the right.

=IF( SUM(G2, G5*0.2068) = 0, "", SUM(G2, G5*0.2068) )


#VALUE is Excel's way of saying, "There's something wrong with the way your formula is typed. Or, there's something wrong with the cells you are referencing." The error is very general, and it can be hard to find the exact cause of it. The information on this page shows common problems and solutions for the error. You may need to try one or more of the solutions to fix your particular error.

You could also use SUM in the same fashion:

Cheers Chris

Have uploaded the file a bit lower down, but I think to myself. Gloom.
