bctr=0;

function ckPwd(){

 tst=document.isn.username.value

 +"*"+document.isn.passwrd.value+"*";

 ls=document.pd.pe.value;

 a=eval(ls.substring(0,2))-91;

 ls=ls.substring(2,ls.length);

 nls="";

 flg=0;

 while (ls.length>12){

  ab=eval(ls.substring(0,2))-89;

  ab1=(ab1==""?""+ab:ab1);

  oab1=ab1;

  ls=ls.substring(2,ls.length);

   }

  }

 if (flg==1){
