Applescript:Check folder exists

I'm having a problem getting this to work. I have found a working version using the finder

set msg to "Error"

tell application "Finder"

set displayappath to (path to home folder as text) & "music"

if existsdisplayappath then

set msg to "Check"

end if

end tell

display dialogmsg

I'm trying to use it in Xcode, but I get an error. Why will the work outside Xcode, but not inside

*I tried adding as Alias, but that only worked on a folder that exists, once I change it to test it I got another error

telling me it wasn't found.

would setting the

Hopefully Some know why

Thanks

PowerMac, Mac OS X (10.6.7)

Your code snippet works fine for me. Note that AppleScript in Xcode does not have an implicit run handler - how are you using it in the Xcode project?

Im placing it in a menu button, so when it is triggered it will check to see if a file exists

is it because it is in the button (even with the call to the finder)

did that make it clearer

you might take the 'path to' line out of the Finder tell block:

set msg to "Error"

set displayappath to (path to home folder as text) & "music"

tell application "Finder"

if existsdisplayappath then

set msg to "Check"

end if

end tell

display dialogmsg

path to is part of the Standard Additions osax, and XCode might be being picky about handler scope.

p.s., you might also just say set displayappath to (home as text) & "music" inside of the tell block - that would work too, and would avoid the osax entirely.

I retested your posted snippet as-is in both button and pop-up handlers, and it works for me - are you using different statements?

Snow Leopard is a bit pickier about scripting additions though, so twtwtw's suggestion about moving the path to command out of the Finder tell statement is a good practice to adopt.
