It's not trivial question. Newsletter service provider offers a hosted on his machine JS script widget that i can put on my website to show contact form. He has a bug in this script. The script adds to document jQuery and jQuery Tools but jQuery is subset of jQuery Tools. jQuery Tools includes jQuery and therefore a conflict occurs and my site using jQuery does not work anymore. $ sign is not working. And because i have other scripts on my site from third-parties i can't change all $-s to jQuery-s.
The service provider dont know when he can fix this issue. And i need this to work so badly. So my question is: do you know any way to fix it from my POV, user of the third party script?
