Error when no Completion date

[bcbuckley13]

Hello,

I've created two columns. One is a Custom column that just adds 30 days to the Reg Date (Due Date). The "Completed in 30?" column is a Conditional column to see if the user completed the course within the 30 days.

If the Completion date is empy, I get a Null, and then an Error in the last column.

Is there any way that I can fix this?

Hi @bcbuckley13 , 

If possible, could you please inform me the detailed error information? if it is caused by the data type, you could try to see whether next step is "change type", then delete this step to see whether it work or not. By the way, if possible, could you please inform me your expression of "Completed in 30" , then I will try to test this in my environment?

Hi @bcbuckley13 ,

You have to start the if with nulls.

The if should be something like if [Course Complete Data] = null then ........

write the other conditions with if else / else.

@camargos88  Thank you! That seems to have fixed it!

From the image, your Due Date is still an Any data type.  Change it to Date to see if that fixes issue.

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.

Pat

Thanks, but that didn't work.

Power Query has a "try...otherwise"  construct that you will want to use.  maybe show your (sanitized) code.

Here's what I had, but still not working.
