Help With Applescript

Im having trouble making this applescript work. Im trying to get it to detect an app runing and then send an email along with quiting the app and displaying a dialog. It also does not detect apps not downloaded from the app store. Any help is greatly appreciated

Here is the script

tell (get system info)

set longName to long user name

set shortName to short user name

end tell

set badApps to {"Messages", "Safari"}

repeat

repeat with badApp in badApps

if application badApp is running then

tell applicationbadApp to quit

display dialog "The Game " & badApp & " is not allowed during school hours please report to I.T. by the end of the day. A log of your activities has also been sent to I.T." buttons {"Report To I.T."} default button 1 cancel button 1 with title "Gaming Alert" with icon stop

end if

end repeat

end repeat
