Open URL and Activate Google Chrome via Applescript

Question

I have the following AppleScript that I wrote many years ago. I use this code to program buttons on my Harmony One universal remote to access online video services via Google Chrome. The code is not working. Google Chrome doesn't launch. I am running the code via RemoteBuddy. The code complies fine, but does not work.

Anyone have any thoughts on what might be the problem, or how I can improve the script to make it work?

tell application "System Events" to set open_applications to (name of everyprocess) if (open_applications contains "Google Chrome") is true then         tell application "Google Chrome" to quit else         tell application "Google Chrome"                 activate                 open location "http://xfinitytv.comcast.net"         end tell         delay 1         tell application "Google Chrome" to activate end if
