Script ofr Length of field

[MST1552]

I am new to this so I could use some help

I am trying to get the length of a field and if the field <>  9 product an error. like "your field has to be 9 charectors.

I have been searching and I can not find anything.

As the custom validation event of the field enter the following (I'm assuming you want to allow the user to clear the field):

if (event.value.length!=0 && event.value.length!=9) {
app.alert("You must enter 9 characters.");
event.rc = false;
}

Edit: Code fixed.
