Call Methods In Tell

Script [14.7.1]:

on completion()
    display dialog "Success"
end completion
tell application "Finder"
    empty trash
    completion()
end tell

Explanation: Here I have created a handler named completion(). But when I call it in the tell block, I get error.

To solve this issue use command of me after calling handler

on completion()
    display dialog "Success"
end completion
tell application "Finder"
    empty trash
    completion() of me
end tell
