Hi Mark,

All your 'simple solution is doing is retrieving the value from Sheet_3!H11. It's no different than using =Sheet_3!H11. As such, it'll require you to input the specific cell address that you want to reference for the carry forward every month.

With Bjorn's solution, as soon as you move last month's sheet to sit between the "FirstTab" and "LastTab" sheets, the formula he gave you will break down (it becomes a circular reference).
