Flow Condition "if field is blank" en French...

[StephaneVedren]

Hi, 

I try make à Flow Condition "If field is Blank", I read the post on this topic https://powerusers.microsoft.com/t5/Building-Flows/Flow-Condition-If-Field-is-Blank/td-p/91665

and I have the impression that in French it does not work ... I tried with Null, Nul, Empty, Vide, "" ... each time the result is False.

Have you got a solution?

Thanks

Hi @StephaneVedren,

Have you tried using the Expression null on the right hand side?

I think ‘null’ you said in the topic, instead of directly typing the string null, use the null inside the Expression, as below:

It work, as below:

In addition, you can also use the empty() function in advanced mode, like: @empty(‘Column name’).

For more details on Functions in expressions, please refer to the link:

HI Barry,

Thanks for your really clear reply. 

I did not understand that it was necessary to put "null" in expression, I tried in simple text.

I am sorry for my response time but it is not my core business, I discover this tool when time allows me.

Thanks for your help.
