invalid number of arguments

(0) ShareShare

Posted on by 42

Hello,

 

everytime i place the simple formula

 

Set(MyVar, "Hello Power Apps")

 

into the OnVisible property of a screen it gives two error messages

CD00131_0-1706701351170.png

 

1. Error:

the first opening Parantheses says: invalid number of arguments: recieved 1, expected 2

This error prevails no matter what i type as the second argument.

 

2. Error:

the comma to seperate the arguments says: The formula contains "Error" when "ParenClose" is expected.

 

 

I suppose the error is very simple and due to my limited experience.

Hope someone can help. Thanks and bye.

    This is a typical bug with European PowerApps developers, as we tend to watch tutorials were the user in the tutorial is American and the syntax there uses , (comma) to do the separation in functions.

    That is odd.

    Do you have any functions before this or after?

    Hi @CD00131 ,

    If you are using European syntax, it would be

    Set(MyVar; "Hello Power Apps")
