Thank you, Jason!! It works! With the global I can now pass variables from a form (not a link) to another page. For the form, I use this:

<form action="forum.cgi" method="POST" enctype="multipart/form-data">
...
<input type="submit" class="submit" name="do=page2;<%hidden_query%>" value="Preview">
</form>

Last thing: In my form I use a multiple select values (<select size="10" name="forums_choice" multiple>). When the user select more than one value I get "ARRAY(0x84a15d8)" when I try to print <%forums_choice%>. When I print <%GT::Template::dump%>, I can see the user values for "forums_choice" like this: "$VAR = [
'forum=1',
'forum=2',
'forum=3',
'forum=4',
'forum=5'
];"

How can I print all the forums_choice values (forum=1, forum=2, forum=3, forum=4, forum=5) in the template? I would like that the values be separated by commas.

Thank you very much!

Sorry for my bad english...
