# SUMIFS: IFERROR Function to Ignore Empty Date Cells Not Working

Options
edited 03/10/23

Hello,

I need to add an IFERROR function to the below formula, but cannot figure out what to input to make it work. I keep getting #INVALID DATA TYPE, #UNPARSEABLE, and #INCORRECT ARGUMENT SET errors.

The goal is to return the total Amount for a particular Team (Retail in this instance) by week for only rows that have an Award Date entered.

=SUMIFS(Amount:Amount, Team:Team, "Retail", [Award Date]:[Award Date], WEEKNUMBER(@cell) = 8)

This is just one of my many failed attempts:

=SUMIFS(Amount:Amount, Team:Team, "Retail", [Award Date]:[Award Date], WEEKNUMBER(@cell) = 8, IFERROR(WEEKNUMBER(@cell) = 0))

Any help would be greatly appreciated!

You're building this in the right direction! Date functions don't like it when there are blank cells or cells with text in a referenced range. The IFERROR would go around the WEEKNUMBER function directly, try this:

=SUMIFS(Amount:Amount, Team:Team, "Retail", [Award Date]:[Award Date], IFERROR(WEEKNUMBER(@cell), "") = 8)

Cheers,

Genevieve
