 <TD><INPUT type="text" name="txt[]" id="txt"/></TD>

You can try assigning the id to the input field, so you can get the input field by ID


var obj= document.getElementById("txt");

if(obj.value==''){
alert("Please enter a value");
return false;
}

You can try same for other fields also.

Hope this helps
