VBA adding Formula to Cell

[jamesmev]

I have a sheet that I need to reference another cell.
If the cell is blank I need it not to have a result.
If the cell has a result I need it to have a result.

I am currently using a formula - however, with the formulas it is causing the workbook to be too large.

I am trying to build the vba and getting an error.

the formula i'm using is:
=IF(D3<>"",F2,IF(C3<>"",F2,""))"

this currently starts on F3.
I need this to loop column C until Row is blank
