Make One Cell Equal a Value in another.

[beetlegossip]

What I am trying to do is to get E2 to equal an input value in F2 without the user changing E2.

E2 equal 2095632 and I am trying to make it Equal F2 which is 12000000. After E2 is changed, then it will in turn change my B2 Value which in turn changes my B3 value.
I'm trying to create a calculator for the GE prices in Runescape to determine how much Runite ore and coal i will need. So far everything is working. I just can't figure out how to make E2 change to F2.
If i'm not being clear enough, feel free to tell me. I just started using Excel today ha ha.

Have you tried:
"=F2" in cell E2?
