It looks like there was never a response, but I was looking at a distantly related issue and came across this thread. If you eliminate the email hidden parameter and just use: dynamic_options="getExperiments(__trans__.user.email)" Would that work for your use case? -John On Tue, Sep 25, 2012 at 8:06 AM, Kohler Manuel <manuel.kohler@bsse.ethz.ch> wrote:

Hi, I have a question regarding the param tag. I would like to pass on the user email to a external python script. I tried to use it like this:

<param name="email" type="hidden" value=$__user_email__ /> <param name="experiment" type="select" label="Experiment" help="select Experiment" refresh_on_change="true" dynamic_options="getExperiments(email)"/>

This does not work. Ideally I would like to have something like this: dynamic_options="getExperiments($__user_email__)"

Has someone done this before?

Cheers Manuel
