Form fields not being passed in IE 6

["dmorand17" <webforumsuser@xxxxxxxxxxxxxx>]

I'm testing out the new form I developed and it's not passing the data to the 
submission page in IE 6.  IE 7 and Firefox work fine, but in IE 6 the 
submission page isn't getting any form data.  

 <cfform action="submit.cfm?func=new" method="post" name="perf_form" 
id="perf_form" enctype="multipart/form-data">
       <div>
         <div class="reqFields">
           <label><span class="style1"><span class="style1">Employee ID:</span>
           <cfinput type="text" name="emp_id" required="yes" class="textInput" 
id="emp_id" size="8" message="Employee Id is required"/>
           &nbsp;
           <input type="button" class="retrieveEmpButton" 
onClick="retrieve_emp('emp_id','');" value="Retrieve Employee Info"/>
           <br />
           Employee Last Name: </span>
           <cfinput type="text" name="emp_ln" required="yes" class="textInput" 
id="emp_ln"/>
