try delete the red items ...
if you need the checkbox items checked by default.
You can write a small script and add it to window.onload eventhandler to load automatically on page load.
It is best to use same value on id and name attributes.
Also, the checked should be best to rewrite as checked="checked" to be validated with (x)html.
<input type="checkbox" id="catcheck1" name="catcheck1" onclick="checkboxs()" checked />
<input type="checkbox" id="catcheck9" name="catcheck9" checked />
