Having problems with an AppleScript
It's a similar error as in your last question:

You can either reuse button_returned and the_results (like you already did in line 6 and 7 &lt;-> 1 and 2):

...
    if button_returned is "More" then set the_results to (display dialog "Second Page" buttons {"FaceTime", "Thank You!"})
    set button_returned to button returned of the_results
end if
if button_returned is "FaceTime" then tell application "FaceTime"
    activate
end tell


or introduce two new variables: button_returned2 and the_nextresults:

...
    if button_returned is "More" then set the_nextresults to (display dialog "Second Page" buttons {"FaceTime", "Thank You!"})
    set button_returned2 to button returned of the_nextresults
end if
if button_returned2 is "FaceTime" then tell application "FaceTime"
    activate
end tell
