=IF(ISBLANK(Dec!E2),YTD!F12,(IF(ISERROR(SUM(((F32)/(DAYS360(DATE(2005,1,1),X1,FALSE)))*(360))*(F13)),"",(SUM((F32)/(DAYS360(DATE(2005,1,1),X1,FALSE))))*(360))*(F13)))

This is my formula, and it works but instead of entering the date (2005,1,1)
manually I want it to pull from cell (H2) but when I reference (H2) I get an
error message telling me that I have too many arguments. How can I make this
work?
