I have the following formula in an excel sheet =IFERROR(IF(V2="",0,IF(W2<>"",W2-T2,Lookups!$L$1-T2)),0) and it does a vlookup to another tab with the prior date. In Power Query I now have a column that shows the Prior Date which is yesterday's date. Now I am needing to understand how I can write this IF Error statement in Power Query. I tried writing it just like I did in the normal excel sheet, but the "", is not recognized in Power Query and I get an error message for Incorrect Syntax. The breakdown is below:

HI @lbrown,
You can take a look at below links about error handling in dax and m query:
For your measure, it can be transform as below measure:
Result = VAR prior = xxxx VAR V2 = xxx VAR W2 = xxx VAR T2 = xxx RETURN IFERROR ( IF ( V2 = "", 0, IF ( W2 <> "", W2 - T2, prior - T2 ) ), 0 )
I'm not clear how you get these variables, so I use var function to define them as variables .

Hi @v-shex-msft
I checked out the links. I'm not quite sure what you mean by the variables andthe var function to define the variables. I entered the formula below into Power Query Editor and received error message:
Expression.Error: The name 'iferror' wasn't recognized. Make sure it's spelled correctly.
Formula I entered in Power Query Editor:
=iferror( IF ( [CONFIRMED_START_DATE] = "", 0, IF ( [CONFIRMED_DROP_DATE] <> "", [CONFIRMED_DROP_DATE] - [REQUESTED_START_DATE], [Prior Date] - [REQUESTED_START_DATE]) ), 0 )
Hi @lbrown,
My formula is dax version, it not works for power query. You also need to input variable before use it..

Hi Xiaoxin,
I didn't realize your formula was the Dax version, but I used this formula and included the correct column names for the variables and this worked. Thanks for your help.
Best,
