Put a - before the last character

[elaaadani]

Hi, I need to put a - before the last character. The field will receive 1234567890 and I need to put 123456789-0
How can I do this?
Thank you very much.

Hi @elaaadani ,

Try this

With(
   {wChar:YourTextControlName.Text},
   Left(
      wChar,
      Len(wChar)-2
   ) & "-" & 
   Right(wChar,1)
)

It does not work. It says it has a number of invalid arguments. Besides an unexpected character in this line

{wChar:YourTextControlName.Text},

 I put this

With(
   {wChar:RutOnombre.Text},
   Left(
      wChar,
      Len(wChar)-2
   ) & "-" & 
   Right(wChar,1)
)

Hi @elaaadani ,

It does work as below using a text box named exactly as your example

What are you doing different?

@elaaadani ,

Are you trying to do it to the same text box as the input? That is a bit more complex. Please confirm That code was designed to write to the source and then display it.

@WarrenBelz Yes, it's the same text box as the input

@elaaadani ,

On the OnChange of the Text Box

UpdateContext(
   {
      varDash: 
      With(
         {wChar: Self.Text},
         Left(
            wChar,
            Len(wChar) - 2
         ) & "-" & 
         Right(
            wChar,
            1
         )
      )
   }
);
Reset(Self)

On the Default of the Text Box

If(
   !IsBlank(varDash),
   varDash,
   Parent.Default
)

On the OnVisible of the screen and at with any Save code (if you do not leave the screen)

UpdateContext({varDash:false})

Hi @WarrenBelz 

It doesn't work for me. I always get this same error !

Number of invalid arguments. 1 was received, but 2 were expected

@elaaadani ,

Here is the exact code I used and it worked exactly as expected in testing
