I need a custom form made with a few variables and conditions:
1. Must be created on the website that I have running now and be linked with the paypal checkout.
2. Form must have a field that allows customer to enter in a unique code in order to checkout - around 150-200 codes (I can enter them myself after the variable is created)
2b. Have unique code, match last name field.
3. Form must have a dropdown menu with 4 options that is also required to checkout.
3b. Depending on the dropdown item selected, display how many products are left, beside the dropdown field.
3c. If the dropdown menu item selected is out of stock, the form cannot be submitted nor there be a checkout page and item should be grayed out + nonselectable.
4. Form information should be sent to database as well as provided email address.
5. Use clean form design, i've already styled the CSS.
