What do I do if that location doesnt exist?

Well, you need to put the jQuery mask script file in the correct location (as specified on that help page). It should exist.

I got it in the correct spot, going to http://server/Forms/js gives me...

And the script is there.

And the mask isn't being applied as you type in the field?

Nope, this is all thats happening...

The library isn't loading or the formatting is not being applied at the appropriate time. So the issue is either the URL in .getScript(), your selector for the phone number's input field, or the event when the code runs.

Are there any other ways to do this that aren't too daunting ?

This is probably the most straightforward way. If you can share the exact JavaScript you're using I should be able to tell you what the problem is.

(function(g){"function"===typeof define&&define.amd?define(["jquery"],g):g(window.jQuery||window.Zepto)})(function(g){var y=function(a,f,d){var k=this,x;a=g(a);f="function"===typeof f?f(a.val(),void 0,a,d):f;k.init=function(){d=d||{};k.byPassKeys=[9,16,17,18,36,37,38,39,40,91];k.translation={0:{pattern:/\d/},9:{pattern:/\d/,optional:!0},"#":{pattern:/\d/,recursive:!0},A:{pattern:/[a-zA-Z0-9]/},S:{pattern:/[a-zA-Z]/}};k.translation=g.extend({},k.translation,d.translation);k=g.extend(!0,{},k,d);a.each(function(){!1!==
d.maxlength&&a.attr("maxlength",f.length);d.placeholder&&a.attr("placeholder",d.placeholder);a.attr("autocomplete","off");c.destroyEvents();c.events();var b=c.getCaret();c.val(c.getMasked());c.setCaret(b+c.getMaskCharactersBeforeCount(b,!0))})};var c={getCaret:function(){var b;b=0;var e=a.get(0),c=document.selection,e=e.selectionStart;if(c&&!~navigator.appVersion.indexOf("MSIE 10"))b=c.createRange(),b.moveStart("character",a.is("input")?-a.val().length:-a.text().length),b=b.text.length;else if(e||

There it is, when I posted this directly into the javascript editor and ran it using your code it worked, I'm just curious why it wouldnt work the normal way!

Oh, I didn't mean give me the contents of the jQuery.mask.min.js file. I meant to paste the code you entered in the JavaScript section of the CSS and JavaScript page in Forms.

If you're saying that when you pasted that into Forms it worked, then it's definitely an issue with the URL you put in $.getScript().

Which is weird because the script file comes up when I go to the URL.

I think the issue is that the .getScript() method doesn't like this URL format.

\\serverName\folder\folder\folder\jquery.mask.min.js'

If you format the URL

http://formsServerName/Forms/js/jquery.mask.min.js

I think it should work.

Also, here is the code.

$(document).ready(function () {

 $.getScript('"http://serverName/Forms/js/jquery.mask.min.js"', function () {
    $(".phone input").mask("(999)999-9999");
 });

  
});
