Woops, I thought I had it.
I've done test after test on this thing and here is what I've come up with. Bare with me, as I'm not as good of a flasher as most of you. If this seems obvious to you then I'm sorry.
I've loaded this fla up and ran several tests on it. The first was to load up an SWF that then loaded the guestbook.swf. This works like a charm. In fact, any site that loads it up as the next file is just dandy.
Here is my problem, I'll explaine my site and give the link as a reference.
page 1 - loads up "loadism.swf" that checks to make sure the user has the latest version of flash. It then loads up 2 more pages.
Page 2 - level 55 "nav.swf" is a navigation for the entire site.
page 3 - level 1 "home.swf" is the content window for the entire site.
From the "nav.swf" page you can load up several other pages which will take the place of the "home.swf" on level 1.
Choose Backlot and level 1 is preplaced by "mainmenu.swf". Next is the Watertower button, which replaces "mainmenu.swf" on level 1 with "watertower.swf".
Inside "watertower.swf" there is a blank mc called GuestBook. When the guestbook button is pushed it loads it up and everything is still hunky dory. It sees the text in the .txt file and it's perfect.
But, when you try and submit an entry it hangs. I understand that it has to do with paths and I also know that it's the actionscript on the submit button. Now, everytime I've posted here I keep being told that it works, that I'm not doing it right. I'm here to tell you that I've changed nothing on the fla but where to find the .txt file and it still is not working. I've ran test after test trying to isolate the problem but to no avail. I've been able to make the guestbook work but only if I load up the "watertower.swf" file from an html and then press the guestbook button. You see, it's only one link back in the chain till the guestbook comes up and it works fine. I've got several .swf files that keep loading other .swf files then finaly I get to the guestbook.
I hope this makes sense. here is the link to the site that I'm speaking of.http://www.ismfilms.com
