# AVERAGEIF function help?

Options
✭✭✭✭

I'm having trouble with the AVERAGEIF function. I have a project intake sheet, and I'd liek to take the average of a number among all projects in the sheet.

I'm attempting to use =AVERAGEIF([Duration of Hold]6:[Duration of Hold]100, >0)), but I can't figure out how to protray the critera correctly to make the formula work.

I want it to only take the average of cells in Duration of Hold, but only the ones that have a number. The column Duration of Hold is calculated based on Start and End date columns. So some rows have a number, but in others the data is still incomplete so some cells say "#INVALID DATA TYPE" because the project hasn't progressed yet. My AVERAGEIF formula is coming back as "UNPARSABLE" currently.

Is there a way to exclude the INVALID DATA TYPE rows in my AVERAGEIF formula? See screenshots below for reference. Thank you!

Ok lets try adding an IFERROR to your formula in the Duration of hold to return a blank instead of an error.

THEN you can do

=AVG(COLLECT([Duration of Hold]:[Duration of Hold],[Hold Start Date]:[Hold Start Date], @cell <> "",[Hold End Date]:[Hold End Date],@cell <> ""))

Hey @Kate Allison,

If you wrap your formula in an IFERROR function, that might remove the invalid data errors:

=IFERROR(AVERAGEIF([Duration of Hold]6:[Duration of Hold]100, >0), "")

See if that works!

@bisaacs It did not work :( It no longer has an error, but now it's just returning a blank cell. It should return a 5 based on the data currently in the sheet.

@Mark.poole changing to <>"" also did not work and still returned #UNPARSABLE.

Maybe there's a way to incorporate ISNUMBER? I haven't figured it out so far this morning.
