Can you try

If(IsBlank(labelAge),Notify("Please enter the value, reason",NotificationType.Error))

Hi @Berihun1 ,

I assume you are referring to the red labels under the text controls. You need  Variable here - firstly initiate it at screen OnVisible

UpdateContext({varError: false})

Now on your Save button OnSelect put this

If(
   Value(YourAgeBoxName.Text) > 0 && Value(YourFamilySizeBoxName.Text) > 0,
   UpdateContext({varError: false});
   SubmitForm(YourFormName),
   UpdateContext({varError: true})
)

The last bit is the Visible on your error labels

varError && !(Value(Self.Text) > 0)

I am assuming here that a number must be entered. Also (if you have not already) set the format to Number

@Berihun1 ,

Exactly as per the code I posted.

• Screen OnVisible
• Button OnSelect
• Visible of your error labels
