jQuery error with script referencing another script

Question

I'm trying to debug an error on this site: www.naijastories.com.

When I click on the 'Donate' link on this page, nothing happens, even though a pop-up is supposed to appear.

Digging deeper and using the IE developer function, I see that the following error is reported:

"Object doesn't support property or method 'prompt'"

The object in this case is the jQuery object, and the error occurs in the /wp-content/plugins/cubepoints/modules/donate/donate.js file.

The line with the error is

var $imp = jQuery.prompt(donatePrompt);

prompt is the missing property.

This is strange, because the prompt property is set in the first line of another js file - /wp-content/plugins/cubepoints/modules/donate/jquery.impromptu.4.0.min.js - which is loaded just before the donate.js file is loaded.

Is the problem that the donate.js file is not seeing what has been done in the jquery.impromptu.4.0.min.js file?

How do I find out why the jQuery global is not being properly populated with the prompt property?

Sorry about that, @arao6. I realised that the link only showed up in authenticated pages, so I've created a special page with the link. I've edited the original post to include a link to the page. — Tola Odejayi

I get "You must be logged in to make a transfer!" when clicking the donate link, no error in console. — arao6

This is quite bizarre. @arao6. You are getting the exact message that you should be getting, which means that this could be a client error. Can you tell me your client setup? I've tried deleting my cache and cookies, but that makes no difference. I've tried this on different browsers, and I get the same error. I've forced a cache refresh of the script from the server - same issue. I'd really love to know what you've done at your own end to resolve the issue. — Tola Odejayi

@arao6, I found the problem - it was an outdated script in an ad which was conflicting with the site's script. Can you make a post so that I can accept it as the answer? — Tola Odejayi

It looks like jQuery.prompt only exists in Chrome, but not in IE, which hints that there's a conflict somewhere with the Impromptu plugin and something else and it's browser-specific. You need to be able to type $.prompt into console and see the function instead of TypeError: Cannot read property 'prompt' of undefined, which I see on your page but not http://trentrichardson.com/Impromptu. Note that this seems to happen in IE and not the other browsers.
