Loading Dynamic Text Breaks Formmail Forms [renamed]

This matter is something I haven’t been able to solve for long and now I’m really desperate to find out an answer.
Here’s a [link](http://www.estudiespai.com/Non_Working Forms.zip) to a very simple zip file (as example) containing the conflictive fla and other files, for those of you who may want to have a look at it.

TO SIMPLIFY THINGS:
It seems that whenever I use a couple of AS instructions to load some Dynamic text from a text file, Forms which are based in formmail, stop working (no matter if these forms are made of dynamic or static text). Why??

INTO MORE DETAILS:
In the attached fla example file here, I’ve simplified things very much by just leaving 2 Forms (one made with Dynamic text and another one without any dynamic text on it).
Very peculiar, if in frame 1 I call the variables from the text file:
[AS]webcontent= “File.txt”
loadVariablesNum (webcontent, 0);[/AS]
the 2 Forms stop working properly: The static one doesn’t even seem to submit data and the dynamic one, it seems data has been sent but data is never received.
As soon as I delete these 2 lines of AS, they work properly again (although of course, no words can be seen in the Form made with dynamic text).

Both submit buttons contain the following AS:
[AS]on (release) {
subject = “Customer Form from your Web”;
recipient = "info@mydomain.com";
loadVariables (“http://www.mydomain/cgi-bin/formmail.pl”, “”, “POST”);
_root.Form.gotoAndStop (“Thanks”);
}[/AS]
So…I don’t have the least idea of what’s going on with this all.
Perhaps any of you could explain what’s wrong with such a simple thing like this and how to avoid this strange behaviour.

Thank you very much!
