Adding @ symbol in front of a number

When I enter:

event.value = event.value != "" ? "@"+event.value : "";

It works perfect, but each time I modify a number in the field it adds an additional @ symbol to the beginning (i.e. @1234, @@2345, @@@3456, etc.).  Other than deleting the displayed @ sybmol in the field each time I change the number, is there a way to stop extra @ symbols from repeating?

I'm not the brightest in Adobe, but I can remember that you can format it with a text field.

Steps for Adobe Pro DC

Prepare form,

go to text field,

Right mouse click,

Choose properties,

Options,

Enter standard value,

insert the character "@",

Conclude.

So it should appear every time you click on the field.

I am sure that there are more suggested solutions, but this is easy and quick.

I hope I could help you.

If that's not what you want, just ignore it.

Thx

Try this as validation script:

event.value = event.value != "" ? "@"+event.value : "";
