{
var objTrs = document.getElementsByTagName("TR");
var j = 0;
for(var i = 0; i < objTrs.length - 1; i = i + 2 )
{
j = i + 1;
if(objTrs[i].name == "SelectTR" )
objTrs[i].style.backgroundColor = "Beige";
if ( objTrs[j].name == "SelectTR" )
objTrs[j].style.backgroundColor = "#ffffff";
}
objThis.style.backgroundColor = "#c6ff00";
}
{
var objTrs = document.getElementsByTagName("TR");
var j = 0;
for(var i = 0; i < objTrs.length - 1; i = i + 2 )
{
