best way, i think so, use alert and check error manually line by line

will u give the code

use this only a little change

add lable

<label><input type="radio" name="grp" value="Yes" tabindex="1">Yes</label>

is problem solved or not

please check,
r u include?or not
<script src="jsfile.js"> </script> in which the init_table() function is defined
