I suggest you a fix on CatViewGrid.php

Hi,
I’m the developer of sliding youtube gallery, another wordpress plugin.
I found out that when a user don’t insert a shortcode for your plugin, the generated javascript cause an error. “paginateVal is not defined” That’s because when this script runs (CatViewGrid.php) like this:

function cg_init_js(){
        global $paginateVal;
        echo '<script type="text/javascript">';
	echo 'paginateVal = '.$paginateVal.';';
	echo '</script>';
	do_action('cg_init_js');
}

If $paginateVal is null then user will have javascript error causing other plugin break. I suggest you to modify the script like this:

function cg_init_js(){
        global $paginateVal;
	if (empty($paginateVal)) {
		$paginateVal = 0;
	}
	echo '<script type="text/javascript">';
	echo 'paginateVal = '.$paginateVal.';';
	echo '</script>';
	do_action('cg_init_js');
}

Thank you.

Luca
