How do include a variable name in an Excel VBA formula ?

Hi Experts,

This is a problem I still haven't managed to get my head round in Excel VBA. I want to multiply a variable (intLatest) by the value in a cell (10th column). However, this formula always returns an error.
   
Range("L2:L" & Cells(Rows.Count, 1).End(xlUp).Row).FormulaR1C1 = "=IFERROR(SUM(RC11-(RC10*intLatest)),"""")"

Any ideas ?

Thanks in anticipation

You need your variable to be between quotes and ampersands:
" & intLatest & "

Range("L2:L" & Cells(Rows.Count, 1).End(xlUp).Row).FormulaR1C1 = "=IFERROR(SUM(RC11-(RC10*" & intLatest & ")),"""")"

you could, in your formula, remove the need for 'SUM':
Range("L2:L" & Cells(Rows.Count, 1).End(xlUp).Row).FormulaR1C1 = "=IFERROR(RC11-(RC10*" & intlatest & "),"""")"
