IF statements that determine calculation

[mrkris1982]

Step 1: E, F and G may or may not have an X in the column. When there is an X, i want to total the number of X's in that row, in column H
Step 2: I has a $ amount. J, K and L have names for headers. I want the value to be the following:
For column J: If X is in column E, then divide I by H and multiply by .65
For column K: If X is in column F, then divide I by H and multiply by .35
For column L: If X is in column G, then divide I by H and multiply by .35

If possible, would prefer to have all cells remain empty/blank until there's data to be calculated.
Whats the easiest way to accomplish this?

TIA

I think it would be easier to help if you could show some sample data, as well as some expected out (explain how, if needed?)

Also, by this "If possible, would prefer to have all cells remain empty/blank until there's data to be calculated.", I presume you mean that you still want the formula there, but it needs to show nothing if there is no answer to be calcd?
