I need some help with a code. I am not a code writer myself.
I need to enter a value in cell B2 and subtract the value of F2 from B2 and place that value into D2. thats the easy part.
This is where I need help. I want to be able to work with the same cells in reverse.
I need to enter a value into D2 and have it add F2 and D2 and place it in B2.
If it makes it easier the value in F2 will be 649
If someone could show me how this is done I would greatly appriciate it.
