Error using updatecontext

[Anonymous]

So basically I want to make a field visible when a field is empty. The following code is inside of my button at OnSelect: 

If(IsBlank(DataCardValue22.Text); UpdateContext({VarError:true}) 

Now on the Visible of my errormessage label I have this: 

VarError

But this gives me an error. What am I doing wrong?

Anyone knows a fix?

If(IsBlank(DataCardValue22.Text); UpdateContext({VarError:true}) 

Yes, your code should be like this 

If(IsBlank(DataCardValue22.Text), UpdateContext({VarError:true}) )

But this VarError variable will get value only when you click that data card so it's better to write your condition in error message 14 label visible property add code as IsBlank(DataCardValue22.Text)

In error message Add some text to check whether it shows message when that data card value is empty

Sorry, I did not explain what I wanted in my application. I do not want the error message to be always visible if that datacard is empty. I only want it to give the error when they click on the "Submit" button of the form. That's why I've used that code.

Okay now I understood

If(IsBlank(DataCardValue22.Text), UpdateContext({VarError:true}),UpdateContext({VarError:false})  )

give like this 

In screen on visible property  add code as 

UpdateContext({VarError:false})

Is it fixed or you have any issue still
