Hide/unhide field based on password in a text field

[Robb Nemo]

Hi, I'm sure this is probably a really easy one, but I'm a newbie to javascript...

What I'd like to achieve is to unhide a hidden field on an Acrobat form based on the correct password being entered into a text field.  Any (polite!) suggestions?

Many thanks in anticipation.

Place this script as a Validation script in the password field:

if (event.value == "PASSWORD") {this.getField("FIELDNAME").display = display.visible;}
else {this.getField("FIELDNAME").display = display.hidden;}

Thank you JR Boulay for the quick response and that worked perfectly.

Simple when you know how... not so if you're a JS newbie! Very much appreciated.
