542402 Need to fix javascript conflict 2

Hi, I have an website and when I click in some links that uses jquery, doesn't work and get this error: Message: Object doesn't support this property or method Line: 17 Char: 11882 Code: 0 URI: [login to view URL] This is the [login to view URL] code: [login to view URL] This only happens when I use this code: [login to view URL] I need to fix this conflict! Both websites are mine, and the priority is to fix this javascript first: [login to view URL] If not possible, then fix this one: [login to view URL]
