Meet the double quotes

Notice that in the example above, both strings are surrounded by double quotes. Both what happens when the string itself has quotes in it. This is for instance the case when the Magento shopping cart is visited, while it contains no items.
The solution is simple: Just use 2 double quotes instead of 1. The translation-line would look like the following:

"Click <a href="/"%s"">here</a> to continue shopping.", "Click <a href="/"%s"">here</a> to go back."
