Hi @sap334,

Give the following code a try, adjust the names where necessary:

If( IsBlank(Label1_4.Text); Notify("Error!";NotificationType.Error;2000); Patch( Table1; Defaults(Table1); {xxx} );; Notify("Success!";NotificationType.Success;2000);; Reset(TextInputName) //Change to the correct text input control name )

Changes:

Label1_4.Text this will reference the control text value

Added the success notification

Added a Reset() function

Note: 1 semicolon is used to separate function parameters (true & false conditions If()), 2 semicolons are used to separate different functions (See Patch, Notify & Reset).

If this solves your question, would you be so kind as to accept it as a solution.

Thanks!

Here is an example of how to do this using syntax from the US. Im not sure exactly how this will translate into your countries syntax as it seems you use ';' where I would use ','

If(IsBlank(Label1_4), Notify("Error!, Texbox can't be blank", NotificationType.Error, 200), Patch(Table1, Defaults(Table1), {xxx}) ; Notify("Success! Data saved!", NotificationType.Success, 2000))

Notice the ';' between the 2 different function calls that is in blue. This separates function calls and allows them both to be executed in the same 'if-true' part of the if statement. They are executed in succession.

@sap334,

To add upon @mmollet comment. This is correct but depends on the syntax used.

According to your code snippet it seems that you are using a European syntax variation, which is slightly different to the syntax most commonly seen on the Forum or on Guides.

The difference is quite straightforward:

Syntax 1: If(condition, true field, falseFunction1; falseFunction2) -> (Comma as a parameter separator, semicolon as a function separator)

Syntax 2: If(condition; true field; falseFunction1;; falseFunction2) -> (1 semicolon as a parameter separator, 2 semicolons as a function separator)

Syntax variant 1 will be most common online - when copying such code, just make sure to change the comma to a semicolon and 1 semicolon to 2. 😊

I hope this helps!
