Module Uploads: dynamic call not working

[magallo]

hi i've been using the module Uploads and this happens to me:

if i add the code like this:

Code: Select all

{assign var=cat value=RAY1304040448}
{cms_module module="Uploads" category=$cat mode="upload"}

the form will show and will successfully process the file

but if i thry to add a variable from url like this:

Code: Select all

{assign var=cat value=$smarty.get.cat}
{cms_module module="Uploads" category=$cat mode="upload"}

I'm able to verify that the value of cat is still the same and in fact,
the form will show correctly, but it will not submit correctly! It's super weird since if the form shows, it means that the parameter category is found.

I don't understand what it could be. I 'd really appreciate some help.
Thanks
