The variable is not defined - Applescript - variables

Question

I made was making this applescript to launch apps with a note:
tell application "Notes"
if exists note starts with applaunch then
set LCommands to {"Launch", "Open"}
repeat with y from 1 to count LCommands
set applaunch to (item y of LCommands)
set AppleScript's text item delimiters to applaunch
set myApp to text items 2 thru 1 of note
set AppleScript's text item delimiters to {""}
set myApp to myApp as text
if y = 1 or y = 2 then
tell application myApp to launch
end if
end repeat
delete note starts with applaunch
end tell
and returns the error "the variable applaunch is not defined" but i defined it. what to do?

Answer 1

You reference applaunch in line 2, but you don't define it until line 5.
Also, your code example is missing the end if that goes with if exists note starts with applaunch then.

Answer 2

You can try something along these lines:
set LCommands to {"Launch ", "Open "}
tell application "Notes"
repeat with aCommand in LCommands
set aCommand to (contents of aCommand)
set myNotes to (notes whose name begins with aCommand)
repeat with aNote in myNotes
set aNote to contents of aNote
set noteName to aNote's name
set AppleScript's text item delimiters to aCommand
set myApp to text items 2 thru -1 of noteName
set AppleScript's text item delimiters to {""}
set myApp to myApp as text
-- If you need to work with the Note's content as plain text
--set noteBody to do shell script "echo " & (quoted form of (aNote's body as text)) & " | textutil -stdin -convert txt -stdout "
my launchDelete(aNote, myApp)
end repeat
end repeat
end tell
on launchDelete(theNote, theApp)
try
tell application theApp to launch
tell application "Notes" to delete theNote
end try
end launchDelete
