Hi,

i have a simple cfform like this.

  <cfform   name="DropDown" method="post"  preservedata="yes"  action="#attributes.pageurl#"  >

     <cfinput type="text" name="txtEmpFName" class="empInfo" required="yes" message="First Name is Empty." value="#variables.txtEmpFName#"/>

     <a href="#attributes.pageurl#?action=add&FamilyMember=2" >ADD Family Membe111</a>

     <input type="submit" class="form_button" name="Empdata" value="Continue">

</cfform>

in the above code, when i click on the submjit button then i can still see the value in the txtempfname. but when i click on the "a href" which calls same page, loosing value in the txtEmpFname (when i click on the link page refreshes and loosing the data.)

Can any one please help me out how to fix this issue.
