is rsforms able to pass php variable in javascript?

in php Script called on form display i setup a query to acces a vlaue in DB
the query itself is working

at the end
echo @myphpvar;

normaly i'll add in javascript something like this

function somefunction() {
var myjavascriptvar = "<?php echo $myphpvar;?>;"
alert (myjavascriptvar);
}

In forms it returns the string "<?php echo $myphpvar;?>;"

How to achieve this?

Did you ever figure out how to get this to work? I'm running into the same scenario.
