Hello,
i want to open a facileform with a link that contains params that will be used inside the form.

So i have done at "before form"
---------------------------------------------------------
$this->execPieceByName('ff_InitLib');
$this->execPieceByName('ff_InitUtilities');

$url = ff_getParam('ff_param_url','www.ccc.de');
---------------------------------------------------------
i will call my form with:
<a href="index.php?option=com_facileforms&ff_name=For mular&ff_border=0&url=www.ccc.de" target="mainFrame">test</a>

Then i want to make a link inside the form that contains $url:
<a href="$url">Download</a>

Any suggestions?

Kind regards icecast
