มีปัญหา createElement แล้ว firefox กับ chome ไม่ทำงานคับ

function fncCreateElement()
{
	document.formgold.elements.count.value = +document.formgold.elements.count.value +1;
	var mySpan = document.getElementById('mySpan');
	var myElement1 = document.createElement('input');
	myElement1.setAttribute('type',"txt");
	var str = 'txt'+document.formgold.elements.count.value;
	myElement1.name = str;
	mySpan.appendChild(myElement1);	
	var myElement2 = document.createElement('<br>');
	mySpan.appendChild(myElement2);
	var mySpan3 = document.getElementById('mySpan3');
	var myElement3 = document.createElement('input');
	myElement3.setAttribute('type',"txt");
	var str = 'val'+document.formgold.elements.count.value;
	myElement3.name = str;
	mySpan3.appendChild(myElement3);	
	var myElement4 = document.createElement('<br>');
	mySpan3.appendChild(myElement4);
	var mySpan2 = document.getElementById('mySpan2');
	var combo_box = document.createElement('select');
	combo_box.name = 'cmb'+document.formgold.elements.count.value;
	for(i=1;i<=48;i++)
	{
		var choice = document.createElement('option');
		choice.value = i;
		choice.appendChild(document.createTextNode(i));
		combo_box.appendChild(choice);
	}
	mySpan2.appendChild(combo_box);
	var myElement5 = document.createElement('<br>');
	mySpan2.appendChild(myElement5); 
}
