Need a textfield to show a text string IF its filled in

You will get an error if you try to add letters to a Number field. You can set it to have no formatting, and then write a custom formatting script that will add "SEK" at the beginning of it.
Alternatively, you can add another field with "SEK" in it and display it when the other field is not empty.

Oh, hello again try67! Thanks for the help last time!
Yes, I have looked in to it a bit more, i have almost figured it out, as you know you can choose the "currency symbol" option, and then choose "kr" (for swedish crowns), but it has to say "SEK". So is there a way to manipulate the "currency symbol" option / or make a custom script and put in "SEK"?

Thanks for the fast answer!

You can't manipulate the currency symbol, but you can create your own script that does something similar.

I have googled after a custom format script, but hasnt been able to find one. You dont have a link to one of thoose scripts? All I need is to see the structure of the script, and then I think I can solve it on my own.

Basically it's pretty simple. Try something like this as the format script:

event.value = "SEK " + event.value;

You might want to consider adding another script that clears the field when the user enters it, or you might end up with multiple "SEK " elements.

It works perfectly! But then it takes away my decimal places and seperator styles, is it possible to ad that to the code aswell?

I found this here on the forum, will, but i couldnt get it to work:

Try the following as a custom format script:

this.getField(event.target.name).setAction("Format", 'AFNumber_Format(2, 0, 0, 0, "$", false)');


The Acrobat proviced forms function call:

AFNumber_Format(nDec, sepStyle, negStyle, currStyle, strCurrency, bCurrencyPrepend)

nDec = number of decimals
sepStyle = separator style 0 = 1,234.56 / 1 = 1234.56 / 2 = 1.234,56 / 3 = 1234,56 /
negStyle = 0 black minus / 1 red minus / 2 parens black / 3 parens red /
currStyle = reserved
strCurrency = string of currency to display
bCurrencyPrepend = true = pre pend / false = post pend

I got it to work! This is the right code:

AFNumber_Format(2, 0, 0, 0, " SEK", false)

Thanks for all the help!
