<script type="text/javascript">
function disen(c) {
var otd=c.parentNode;
var otr=otd.parentNode;
for (var j=1;j<otr.cells.length;j++) {
if (!c.checked) {
otr.cells[j].getElementsByTagName("input")[0].value="";
}
otr.cells[j].getElementsByTagName("input")[0].disabled=!c.checked;
}
}
function doit() {
var otbl=document.getElementById("tblid");
var sum, cv, nrow, ncell;
for (var i=1;i<otbl.rows.length-1;i++) {
sum=0;
ncell=otbl.rows[i].cells.length-1;
if (otbl.rows[i].cells[0].getElementsByTagName("input")[0].checked) {
for (var j=1;j<ncell;j++) {
cv=otbl.rows[i].cells[j].getElementsByTagName("input")[0].value;
if (cv.length==0||!/^\s*[+-]?\d*(\.\d*)?\s*$/.test(cv)) {
otbl.rows[i].cells[j].getElementsByTagName("input")[0].value="";
cv=0;
}
sum+=parseFloat(cv);
}
otbl.rows[i].cells[ncell].getElementsByTagName("input")[0].disabled=false;
otbl.rows[i].cells[ncell].getElementsByTagName("input")[0].value=sum;
}
}
nrow=otbl.rows.length-1; //last row
ncell=otbl.rows[nrow].cells.length-1; //last row's last cell

}
otbl.rows[nrow].cells[j].getElementsByTagName("input")[0].value=sum;
//var s = sum;
