Custom Capabilities (hardcode url member options page)

Hi

After following the custom capabilities videos by Jason I have added the following code to my functions.php file:

add_action ("template_redirect", "my_custom_capabilities");

function my_custom_capabilities ()
	{

		if(is_category ("blink_182_guitar_course") && !current_user_can ("access_s2member_ccap_blink_182_guitar_course"))
			{
				header ("Location: ". S2MEMBER_MEMBERSHIP_OPTIONS_PAGE_URL);
				exit ();
			}

		else if(is_category ("techniques_guitar_course") && !current_user_can ("access_s2member_ccap_techniques_guitar_course"))
			{
				header ("Location: ". S2MEMBER_MEMBERSHIP_OPTIONS_PAGE_URL);
				exit ();
			}

	}

However instead of using the same membership options page for both product/membership access levels – I would like to redirect to a different URL for each product.

I tried replacing part of the code… from this:
header (“Location: “. S2MEMBER_MEMBERSHIP_OPTIONS_PAGE_URL);

TO

header (“Location: “. fastfingerfreddy.com);

but this forced my entire site to not load so clearly I was doing something wrong. Can you please let know which part to remove and where I should enter my address – eg http://www.fastfingerfreddy.com

Please be as detailed as possible, do I need to use speechmarks etc

Also, can I just confirm that the entire code I have used above is actually correct as on the video by Jason (https://www.youtube.com/watch?v=h7zBH938VbA), the code he copies from the API Scripting section is different to the code he then edits on the functions.php file – please watch the video from around the 7min mark and you’ll see what I mean

Thanks
Rich
