Need help on setting parameters for tabbing on a worksheet (possible macro?)...

Not sure if this is a macro issue or not...

My problem is that I have 3 sections on one worksheet, one on the left, middle, and right, and when tabbing through the worksheet, I want the tab key to first go down the section on the left, then go to the section in the middle tabbing from left to right, and then the section on the right.

Another way of saying this is I want the path that the tab key follows to be:

C10, C12, C13, H7, J7, H8, J8, H9, J9... all the way down to H42, J42, then start at the top of O7, Q7, O8, Q8... all the way down to O42, Q42, and then the next tab would bring you back to C10.

Those are the only cells I want the tab button to go to, and in that order.
