making a script error illegal characters

[Herbie000]

I have a script that makes folders, and subfoldres, it askes for the user to type in a name for it. What I need is a way that it will error out and stop running the script and also display a dialog box as to why (illeagle character) such as *,+,< and so on.

I can get it to error but it still makes the foler, there are about 25 of these characters I wish for the user not to use.

on run
tell application "Finder"
activate
et job_number to text returned of (display dialog "Enter the Job Number:" default answer "" buttons {"Cancel", "Ok"} default button 2 with icon 1)
if job_number contains "*" then (display dialog "You entered an illeagl character" buttons {"Ok"} default button 1 with icon 2)
end tell
end run
		

If I put “if job_number contains “*” then error” it will error but then how do I get my dialog box?

Any help would be appericated.

Try this:

–Open this script in a new Script Editor window.

set job_number to “”
set the_error to “”
repeat
if the_error is not “” then
beep
set the_icon to 0
else
set the_icon to 1
end if
set job_number to text returned of (display dialog the_error & “Enter the Job Number:” default answer job_number buttons {“Cancel”, “Ok”} default button 2 with icon the_icon)
set the_error to “”
set illegal_characters to (characters of “*+<>”)
repeat with this_char in illegal_characters
if job_number contains (contents of this_char) then
set the_error to "You entered an illegal character: " & (contents of this_char) & return & return
exit repeat
end if
end repeat
if the_error = “” then exit repeat
end repeat
return job_number
