Good Evening everyone

My name is Tracy and I am new to this forum. I have a problem with a formula and I hoped that someone would be able to provide some valuable assistance. I would like to point out that although I use excel I only have a basic knowledge of formulas.

I have a spread sheet for our monthly income and expenditure. I have 24 columns made up of budget and actual figures on a month by month basis, so column A for example would be April Forecast and B would be April Actual, and so on.

I have been able to add up the Forecast for the year in a total column running April - March, and likewise the Actual columns. However, what I also need is to be able to show a revised forecast. So for example April revised would be April actual plus May-Mar forecast, then after entering May's figures for the month the revised forecast would be April & May actual plus Jun-Mar forecast, and so on for the remainder of the year.

I have tried everything to get this to work, but to no avail.

Any suggestions would be most gratefully received.

Kind regards
Tracy
