Hi @natanz ,
Is this PowerAutomate issue ? 😊 I think is the wrong community, but let me give a shot.
There is no function called IsBlank() in PowerAutomate, you should use empty() function to check if your value is empty.
Also for string in PowerAutomate you have to use single quote ' , not double ".
And last you have as a result a string in one branch of the if clause and an integer in the other one. You can confuse the system with this approach.
Hope it helps !
