Error with regex in jquery

Question

I want to validate my textbox on keypress event. As I am newbie with jquery, I searched on google and found one jquery plugin named 'limitkeypress'.

This is my code:

$(document).ready(function() {
    $("#title").limitkeypress({ rexp: /^[A-Za-z]*$/ }); 
});

Plugin library is:

http://brianjaeger.com/process.php

It's giving me the following error

$("#title").limitkeypress is not a function

When I checked the library on jsfiddle it shows me dozens of errors. Is there any other validation library or plugin?

EDIT Thanks everyone for your valuable comment. Finally I got the solution. Though I was including file correctly. but don't know Y it was not working. I wrote jQuery.noConflict(); and all the problem is solved. What exactly it work. Please let me know, though I read but doubt still I have doubt.

Did you try their demo on a simple page to see if it worked or if it's just your application? Did you make sure their JS is included and downloaded properly in Firebug? — WattsInABox

If you're including some other library besides jQuery on your page such as ExtJS or prototype, some of the function calls may overlap. The noConflict() function namespaces the jQuery calls so that no accidental overloading will occur. — WattsInABox

regexp is ok: 'buGaGa'.match(/^[A-Za-z]*$/);
$("#title").limitkeypress is not a function probably you forget to inlude library or wrong path.
Check it in Firebug( Net -> All ) lib must be highlight in black, not red.

Nopes it doesn't shows me anytype of error using firebug.. Even this error is shown by firebug.. chrome shows me..#object has no method limitkeypress..

add <script type="text/javascript" src="http://brianjaeger.com/jquery.limitkeypress.js"></script> if error still exists, may be plugin is incompatible with your jquery version, on site of plugin using jquery 1.3.2

Problem still continue..Ya its written for jquery1.3.2 showing on site and now I am using. Jquery's latest version how can I make it compatible..?

Look at Andy's answer, there is no compatibility problem. I advise to you to remove all javascript except limitkeypress, may be error not in plugin.

Made a demo: http://jsfiddle.net/tTASy/ plugin seems to work fine.

Check your path to the script. if you paste a link to your page we could help you more specifically.

You can do this in jQuery like this without the plugin..

$("#your_textbox").keypress(function() {
  var length = this.value.length;
  if(length >= MIN && length <= MAX) {
    $("#your_submit").removeAttr("disabled");
    $("#your_validation_div").hide();
  } else {
    $("#your_submit").attr("disabled", "disabled");
    $("#your_validation_div").show();
  }
});
