api.data.calculate

Im trying to create a formula for one of our Statistical Cal accounts.  Its a derivation of of a calc we already have.  However the line will no compile even when I copy the existing formula completely.

Return api.Data.GetDataCell("(Divide(A#1200:I#None,A#TTM_Net_Sales_wo_IC)) * 365)")

I can compile the existing account without issue, but when I copy this formula into the new account I get an error
