How to evaluate a scriptlet variable in EL?

Question

I was wondering if there was anyway of using JSP in <c:if> statement.

E.g.

<c:if test="${ param.variable1 == 'Add' <% JSP variable clause %>}">

So I want my JSP variable to checked against as well.

Any suggestions? I have tried ignorantly just sticking in the clause, obviously it did not work.

Thanks
