var row = document.createElement("TR");
var cell1 = document.createElement("TD");
var inp1 = document.createElement("INPUT");
var combo1=document.createElement("select");
var combo11=document.createElement("option");
var combo12=document.createElement("option");
var combo2=document.createElement("select");
var combo21=document.createElement("option");
var combo22=document.createElement("option");
var inp2=document.createElement("INPUT");
var inp3=document.createElement("INPUT");
inp2.setAttribute("type","text");
inp2.setAttribute("value","no");
inp2.setAttribute("size","3");
inp3.setAttribute("type","text");
inp3.setAttribute("value","amount");
inp3.setAttribute("size","7");
combo1.setAttribute("name","cmbgroup");

}
var hgroups=document.frmdesilt.cmbgroup.options.length
//document.write(groups);
