Glad to see you posting in the forums! That is a great step toward becoming a developer.
I highly recommend you take the Treehouse course on Flask. It has a lot of great information to get you started in web programming. Kenneth Love is one of the best Flask teachers you can find, and you may find a Flask app slightly easier to get running consistently than straight CGI. And, the cool thing about Flask is it can be deployed as a CGI script as well as in other scenarios. Treehouse workspaces have everything you need to get up and running.
That being said...
I can see you are doing some old-school Python CGI programming-- let's build on that...
There are multiple problems you will need to address before it will work:
- you are missing the <form method="GET"> tag at the beginning of the form part of your HTML
- your input elements need a name parameter which matches its getvalue ("image", productID", "quantity", "price", "select_size")
- you should include an <input type="submit"> button.
- you need a closing </form> tag.
- you might want to look carefully at the CGI programming link below to get the output string to format the way you intend.
Here is a basic treatment of Python CGI programming:
