	element_names["req_subject"] = "বিষয়" // বিষয় = Thread Subject
	element_names["req_message"] = "বার্তা" // বার্তা = Your massage

	if (document.all || document.getElementById)
	{
		for (i = 0; i < the_form.length; ++i)
		{
			var elem = the_form.elements[i]
			if (elem.name && elem.name.substring(0, 4) == "req_")
			{
				if (elem.type && (elem.type=="text" || elem.type=="textarea" || elem.type=="password" || elem.type=="file") && elem.value=='')
				{
					alert("\"" + element_names[elem.name] + "\" is a required field in this form.")
