So many things can be the cause here. Now let's start by checking whether the function is getting called at all: change to


[HTML] function validate(a,b) {
alert("Getting called");
if(document.getElementById('a').value == "" && document.getElementById('b').value == "")
{
alert("The Fields cannot be empty");
return false
}
else {
return true;
}
}
[/HTML]

Not sure if this matters I didn't test but you may want to use OR to check if those fields are empty.
