JSP EL problem

Subject: JSP EL problem

Hi

I am new to JSP Expression Language. I am trying a simple IF statement but cant get it to work. Does anyone one find anything wrong with this condition:

c:if test="${param.fname = null} || ${param.lname= null} || ${param.age= null}">

<jsp:text>Please enter the correct values</jsp:text>

</c:if>

This is a part of the code for a simple form which gets first name,last name and age from the user. Using the IF condition in EL , I want to put a validation in the form, that does not allow the user to leave any of the above mentioned fields blank. Suggestions plz
