Wordpress Conflict Fix

Hey there, I have two scripts that I am running on a wordpress blog. One is a plugin that places a popup when users enter the site. The other is a bit of javascript that redirects users who exit the site. I want them to work both together.. At the moment the plugin works fine, but when the user leaves the site.. the other script does not work.. but if they refresh the page.. the plugin does not work ( as its been set that way ) and the other script works fine. I would like them both to work together.. so that the entry popup works, and if the user closes the entry popup, and then tries to leave the site the exit popup works as well. I need this done asap.. Cheers..
