changing the action of a form

[bernie.nmsu]

I have a form which contains two radio buttons to run a report. The radio buttons are called selection. Based on the user selection, the value becomes dept or date.

I want to change the action of the form based on the selection. I am attempting the following if statement which fails.

        <form name="form1" method="post" 
                  <?php 
                      if  
          ('selection' == "Dept")
 {
 action="classRosterReportDept.php"
 }  	
        else
 {
 action="classRosterReportDate.php"  
 }
 ?>
                   >

Can someone let me know if Dreamweaver has something built in already to do this or on how to fix the php code. I receive the following error:

Parse error: parse error, unexpected '='

**SOLVED**

Performing to change behaviors on the action on the selection of the radio buttons resolved the problem.
