@pyroJun 30.2003 — Try something like this:

&lt;html&gt;
&lt;head&gt;

&lt;script type="text/javascript"&gt;
function validate(frm) {
re = /^w{2}[-](d{4}[-]){2}d{2}$/;
if (!re.test(frm.mytext.value)) {
alert ("That is an invalid entry");
}
}
&lt;/script&gt;

&lt;/head&gt;

&lt;body&gt;
&lt;form name="form1" method="post" action="" onsubmit="return validate(this);"&gt;
&lt;input type="text" name="mytext"&gt;(ie. xx-1111-1111-11)
&lt;input type="submit" value="Submit"&gt;
&lt;/form&gt;
&lt;/body&gt;
&lt;/html&gt;

@pyroJun 30.2003 — Charles -

Your's doesn't allow for two digits at the end of the string.

Did you mean this:

(!/^w{2}-d{4}-d{4}-d{2}$/.test(this.value)

@CharlesJun 30.2003 — [font=georgia]Admittedly my eyes are bad and getting worse, but the way I read the request only one trailing digit is required. But just to be sure I'm going to brew up a pot of tippy gold Yunan. That always helps.[/font]

@pyroJun 30.2003 — lol... know what? It's not you, it's me... :rolleyes: You were right. One digit at the end...
