set RTFtext

[Michael Monos]

Help!

I have no idea what I am doing, and after searching through the 
archives of the mailing lists without
finding an answer, I thought I would try to get an answer via a post 
here...

with a button on anyCard, with the script (OS X):

on mouseup
	set the rtftext of field "text" to URL "file:filename.rtf"
end mouseup

This produces no result -- do I need a path? Do I need to declare the 
path of this filename somewhere?

What is the path structure needed in OS X? I understand file paths, but 
even when I enter the full path (as I understand it),
I get no result.

Any help would be appreciated.

Thanks
