I am using the below code click button to patch only if the fields are Not blank.

But the every first time, even the field not blank, it bring notification. In the second click it works.

Could not understand, what is the reason.

Is there any other way to Test the blank fields, should I used the function Blank(TextBox2_1.Value)

please guide

Below is my code

If(Len(TextBox2_1.Value) = 0 || Len(TextBox2_12.Value) = 0 || Len(TextBox2_20.Value) = 0,
Notify("Cannot Save !!!  As  Form No, Model, Serial No  Fields Cannot be Blank", NotificationType.Warning,3000),
Patch(

Hi,

yes you are right, you should use the Blank() function or compare the string to the built-in IsBlank() function.

If(TextInput1.Text=Blank() Or IsBlank(TextInput1.Text); true ; false )

Len() is actually the better option is it covers both Blank(() and Empty() - a text box can contain an empty string. I think your issue is actually the modern control - to test this, try Classic Text Inputs and see if that works.
