Q:

Is there any way to pass a variable through a link other than something like "?token=827273"

Here's how the app works:
The business will put our recording widget on their website with our embed code. Their users will record a video and after that video has been approved, an email will be sent to the user who recorded the video with a link to the page where the business has added our embed code to display those videos.
The embed code displays a php file, which knows which video to display based on a token value in the url. We add ?token=<?php echo $token ?> to every url.
Our newest test subject has the url structure, www.url.com/Page.asp?NavID=3786, and adding ?token=<?php echo $token ?> messes up their NavID and displays an error. 
Without the ability to change their code, is there another way to pass our $token variable (through the link or otherwise) without messing up their variable?

A:

To pass multiple $_GET variables simply use & between them instead of a second ?.
www.url.com/Page.asp?NavID=3786&token=MyToken
