Adding the Button
Next up, you need to add the cart to your website in Expression Web. Again, this is pretty easy. All you need to do is select the code on the following page. Make sure every single letter or symbol is selected, then press CTRL and C.
Return to Expression Web and paste the code. To do this, you need to find the spot where you want it inserted in Design View.
Once you’ve found the perfect spot, just click so the cursor remains there and switch to Code View.
Immediately after entering Code View, hit CTRL and V to paste the PayPal cart button. You can move the button around in both Code View, by cutting and re-pasting, or in Design View by dragging the button around.
The great thing about using this tactic is that it doesn’t require a lot of knowledge about HTML, and will take you far less than creating an entire shopping cart and purchase system yourself.
