[jQuery] Error '$this' is undefined

[Daybreak0]

Hi all,

I have the following html, of which I want to replace the text "Cart"
with "My Shopping Bag" (The Veiw Cart text is near the end)

Code:
<div class="cart-summary"><span id="catCartSummary" quote="False"
vertical="False"><table cellspacing="0"
class="cartSummaryTable"><tr><td class="cartSummaryItem">1 item(s),
Total: &#163;0.00 <a class="cartSummaryLink" href="/
OrderRetrievev2.aspx?CatalogueID=45965">View Cart</a></td></tr></
table></span></div>


Now I need the ability to actually choose the actual text I want to
replace, as there is other text, where I can not replace the whole
text line due to different numbers produced on the fly, so I cant use
the following, which does work.

Code:
$(".cartSummaryLink").html("View My Shopping Bag'");

I need to use the following one, but my experience is poor

Code:
$('.cartSummaryLink').val( $this.val().replace('Cart','My Shopping
Bag') );

I get the following error
Message: '$this' is undefined

any help will be appreciated.
Thanks
John
