help making SKU: field a text link

So I decided to try and use the SKU: field display a clickable link on my product page.(next to model, average rating, etc...) I think I almost have it. What I want is to have it display:

SKU: "click here"

and when they click on "click here" it will take them to what ever link that I entered in for SKU from admin. I went to
/catalog/view/theme/default/template/product/product.tpl and replaced the code: With But it didn't work, it comes out blank, as in

SKU: "blank"

You can see what I mean here:

I think I am close, just need a little help here, I I suck at php. Thanks!

What you are trying to do should work okay but you will need to have 'http://' at the beginning of your link otherwise it will assume that you are referencing within your site. You may also want to change the target so that it opens in a new window otherwise you will completely divert them from your site.

So, it would be something like:

That works... Thank you very much.

Is there a way that I can make the text not show if nothing is entered in the SKU field. I am using it to link a companys website, and if the company doesnt have a website to link to, I would like the text not to show. I tried

<?php if ($product_info['sku']) { ?>

but no good.

You can do this but your condition will always return true.

It needs to be: i.e. if the sku is not empty.

that one didnt work, gave me an unexpected $ error in the line <?php echo $footer; ?>

did you add a corresponding:
to close the 'if' structure ?!

Nope I didnt, and now that I did, it works... thanks!
