Add chart link next to a variant selectbox

HI Hiakshop crew !!

Ok,so I have many different variants.ie:Colors, sizes,patterns, etc...

What I attempting to do is add a link right after the variant selectbox. And that link is in the module and when clicked opens custom modal. So , in other words the link and modal is all contained in the module I'm trying to load conditionally.

So I need to editing/customize the products/show_block_characteristics
All I want to do is get the variants field label value (ie.: Colors.Sizes,etc) and using a switch statement load the corresponding module after the selectbox .
I included a screenshot, as it will will be obvious to see what I'm trying to do.

I was thinking of just adding a switch statement to load the corresponding module.
Example only - so variables might not be correct.

switch ($variants_name) {
	case 'Colors':
		echo JHTML::_('content.prepare','{loadposition colorchart}');
		break;
	case 'Sizes':
		echo JHTML::_('content.prepare','{loadposition sizechart}');
		break;
	default:
		break;

Thanks Jerome !!

HUm, maybe i spoke too soon.

It worked when I edited the core file,
but now that I copied over that function "display FE" into the view, it's not working.
I wonder what I'm missing something?? Hum?
I tried extending the class but that didn't work.

Once I've added the function to the show_block_characteristics.php is there anything else to do, besides my custom code?
I'm not exactly sure to how to override that function? Thought it would be obvious, but now I realize it not.
Help?

Thanks a lot Jerome !!!
Got it working.

I don't think I would have ever guessed to use

include_once $originalFile;

In the end I found a simpler way using "NoNumbers - Advanced modules manager Pro", you can set your rules in there; quite easily actually, without having to know any code (for those who can't ).

Peace.
