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 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");

combo2.appendChild(combo22);
var cell2 = document.createElement("TD");
cell2.appendChild(combo1);
var cell3 = document.createElement("TD");
cell3.appendChild(combo2);
var cell4 = document.createElement("TD");
cell4.appendChild(inp2);
var cell5 = document.createElement("TD");
cell5.appendChild(inp3);

row.appendChild(cell2);
row.appendChild(cell3);
row.appendChild(cell4);
row.appendChild(cell5);

tbody.appendChild(row);
}

var hgroups=document.frmdesilt.cmbgroup.options.length
//document.write(groups);
var group1=new Array(hgroups)
for (i=0; i<hgroups; i++)
group1[i]=new Array()

group1[0][0]=new Option(" ")
group1[0][1]=new Option("News.com")
group1[0][2]=new Option("Wired News")

group1[1][0]=new Option("CNN")
group1[1][1]=new Option("ABC News")

/*group[2][0]=new Option("Hotbot")
group[2][1]=new Option("Infoseek")
group[2][2]=new Option("Excite")
group[2][3]=new Option("Lycos")*/

var temp=document.frmdesilt.cmbitem
function redirect(x){
/*for (m=temp.options.length-1;m>0;m--)
temp.options[m]=null*/
for (i=0;i<group1[x].length;i++){
temp.options[i]=new Option(group1[x][i].text)
}
temp.options[0].selected=true
}

</script>
</head>
<body>
<input type="button" value="AddGroup" size="-4" onClick="addRow();">

The advice is actually good. But be aware that Thomas Lahn has a
personality which is more or less unique here, though resembling that of
too many Germans of a two or three of generations ago. Others are
generally more tolerant, at least initially.

You seem to be a foreigner; please be aware that, while we do not expect
good English to be achieved by all foreigners, we do prefer to see it
attempted. You should know, for example, about the use of capital
letters.
