Cobrowse launcher script error

Why am I receiving an error message "cannot read property 'session' of undefined" on my chat launch page?


Chat, Cobrowse


When you go to a page with the Cobrowse launcher script, pressing F12 for debugging tools and clicking on the console tab, an error similar to the following error message is appearing:

"SCRIPT####: Unable to get property 'Session' of undefined or null reference."


"uncaught TypeError: Cannot read property 'Session' of undefined at......"


This type of error will occur when two launcher scripts have been included on the same page.  Often if you have manually placed the launcher directly on the page in addition to including a template (header or footer) that is also placing the launcher on the page you will end up with two launchers on the page.  Removing one of the scripts from the page will correct the problem.
