Can't Select '0' As a Numeric Option

I’m using a theme from Templatic.com called Real Estate 2. Overall the theme is great but I’m running a problem that the developer doesn’t have a solution for.

There is a custom field that is built-in which allows the specific post_type (in this case a property listing) to select a bedroom count. However, 0 (Zero, as in Studio/bachelor pad) is not an included option. The developer said the reason the number ZERO couldn’t be included is because it’s not a numerical value. Below is the area in the custom_function.php file that the developer said he tried to make edits to but couldn’t get it to work.

Can anyone see based on the code below where I can make a change so I can add 0 as an option?

Thanks for any help.

<?php
}
function get_max_number_bedrooms()
{
	$generalinfo = get_option('mysite_general_settings');
	if($generalinfo['max_bedrooms'])
	{
		return $generalinfo['max_bedrooms'];
	}else
	{
		return 10;
	}
}
function get_bedroom_dl($proprty_bedroom)
{
	$i=1;
	$max_bedrooms = get_option('ptthemes_bedrooms');
	for($i=1;$i<=$max_bedrooms;$i++)
	{
		$addval = '';
		echo '<option ';
		if($i==$proprty_bedroom)
		{
			echo 'selected="selected"';
		}
		if($i==$max_bedrooms)
		{
			$addval = "+";
		}
		echo ' value="'.$i.$addval.'">'.$i.$addval.'</option>';
	}
}
