Average of project completion for current year

Dustin.Crabtree

I'm trying to average the "%" column based on rows that are only in quarter 1 (Quarter Identifier = 1), and have a completion date that is the current year.

I'm trying to make this sheet roll over year-after-year and am trying to stay away from specifying "2019".

The formula I have currently is:



=AVG(COLLECT([%]:[%], [Quarter Identifier]:[Quarter Identifier], =1, [Completion Date]:[Completion Date], =YEAR(TODAY())))

 

But it's giving me an output of "#Divide by zero" even though I have dates in quarter 1 that are the current year.

Am I using the YEAR function incorrectly?

Attached is a screenshot to hopefully better explain the sheet information.

Just wanted to update this, figured out what I was doing wrong:

=AVG(COLLECT([%]:[%], [Quarter Identifier]:[Quarter Identifier], =1, [Completion Date]:[Completion Date], YEAR(@cell) = YEAR(TODAY())))
