What I am looking to do is the user enters data into a field with an arbitrary mask (AAA99999A99999) and I wand to take the last 6 characters and have it populate into another field automatically.  I haven't been able to find an answer on my own.

Thanks for any assistance.

HI,

In the validate function of the field with the mask, you can add code something like this

var lastSix = event.value.substr ( event.value.length - 6, event.value.length);

// change Text2 to the name of the other field

this.getField("Text2").value = lastSix;

Hope this helps
