Edit text in SWF file

I need to change text in a SWF file. I was able to do it (using sothink), but when I saved it, I got an error saying "actionscript contains errors". The file is actually a flash form page. When I tried to upload it to the web, the form wasn't functioning properly. I need someone who can edit the file, send it back to me so I can upload it and ensure it's working properly. It's a small job. Budget $10 firm.
