help with looped equation

[joemomma]

I am really struggling here with this (what seems) fairly simple labview problem.  I have a set of equations that rely on the answer of the previous other formula and so forth.  I can do this easily enough in excel.  I tried to recreate this function in labview and have been really struggling to get it to work.  I have tried using while loops and for loops, which I think is what I need to do here, but I haven't had much success.  Anyways, I attached the spreadsheet with the two formulas, a .png showing the relationship of the formulas in the spreadsheet, and my .VI.  Thanks for your help in advance.

You need both a loop and a shift register.
