Hi all,

I have problem with Set in following case.

SelectedLanguage - is global variable

It is "green" in IsEmpty (recognized as variable), in Set commands (bold) it is not in "green" and SET does not work...

What is "funny", is when you write the variable name behind semicolon it is recognized, but it is obviously incorrect syntax.

If((Or(Left(Language();2) = "en";Left(Language();2) = "cs") && IsEmpty(SelectedLanguage));
 Set(
 SelectedLanguage;
 Left(
 Language();
 2
 )
 );
 Set(
  SelectedLanguage;
 "en"
 )
);;

You might want to consider replacing your IsEmpty with IsBlank as in this case you are trying to determine if the variable is blank, not if it is empty. IsEmpty on "" will always be false. IsBlank on "" will always be true.

I hope that is helpful for you.

Thank you I will correct that, but evaluation is not the problem. Problem is set, that does not work and does not matter whether it is true or false.....

Are you saying that nothing gets set in the variable? According to your formula (with the IsEmpty) in it, it will always have "en" in it.

I have tried that exact formula (with the IsEmpty and IsBlank) to test, and in noth instances, the variable ends up with "en". Of course, my language setting is EN anyway so I suspect it to be. But if I alter the first Set to show something different just to test, the formula works just fine.

Also, just to be sure, make sure you don't have any Context variables on that screen called SelectedLanguage. Having a context of SelectedLanguage and a Global of SelectedLanguage is posisble in PowerApps, but causes a lot of confusion.

Hi @TomasZubov ,

I have made a test, and the issue is confirmed on my side. The screenshot as below:

It is the normal color rendering representation of Variable within PowerApps Studio for web.

When you initialize/update a variable within PowerApps Studio, the color of the Variable name would be the default color -- Black. Only when you use the initialized Variable within other formulas, the color of the VariableName would be rendered as a different color (Global variable rendered as "Green", Context variable rendered as "Blue").

If you want the color of the Variable name to be rendered as corresponding color when you initialized/updated the variable, I afraid that there is no way to achieve your needs in PowerApps currently.

If you would like this feature to be added in PowerApps, please consider submit an idea to PowerApps Ideas Forum:
