Hey thanks. i got round it in the end with this - had a few other spin offs from this but this is the crocks of it:
if ((crmForm.all.p1_onstop.DataValue==1))
{
//Set the section color to red but keep field colour background white
var list = crmForm.all.p1_onstop;
var option = list.options[1];
option.style.backgroundColor = "#FFFFFF";
option.style.borderColor = "#FF0000";
option.style.color = "#000000";
crmForm.all.p1_onstop.parentElement.parentElement.parentElement.style.backgroundColor = "#FF0000";
}
//set back to normal if not on stop
if ((crmForm.all.p1_onstop.DataValue==0))
{
crmForm.all.p1_onstop.parentElement.parentElement.parentElement.style.backgroundColor = "";
}
cheers
Matt
