This will create the following form element:

<FORM METHOD="post"
ACTION="http://www.yourdomain.com/Merchant2/merchant.mv?">
Type the domain of your site followed by the path to Merchant.

<INPUT TYPE="hidden" NAME="AttributeCode1" VALUE="option">
If the product has one Attribute, type the line as shown. If this was the second attribute for the product, change AttributeCode1 to AttributeCode2.

<SELECT NAME="AttributeValue1">
<OPTION SELECTED VALUE = "opt_color_code_1">Blue</OPTION>
<OPTION VALUE = "opt_color_code_2">Purple</OPTION>
<OPTION VALUE = "opt_color_code_3">Green</OPTION>
</SELECT>

For each option of the attribute, create an <OPTION VALUE = "option_code">Option Name</Option> line. Replace "option_code" with the Option Code of your option.
(Make sure the first Option Value has the SELECTED parameter.)

<INPUT TYPE="hidden" NAME="AttributeCount" VALUE="1">
Enter as shown. If you had two Attributes, and created two sets of <SELECT NAME=> and <OPTION VALUE>s, then you'd changed the VALUE parameter of "1" in this line to "2"

<INPUT TYPE="hidden" NAME="Action" VALUE="ADPR">
This tells Merchant to add the product and selected attribute/option pair to the Merchant basket.

<INPUT TYPE="hidden" NAME="Screen" VALUE="BASK">
This tells Merchant to send the user to the Merchant Basket screen.

<INPUT TYPE="hidden" NAME="Store_Code" VALUE="Your_Store_Code">
Type the store code of your store for the VALUE field.

<INPUT TYPE="hidden" NAME="Product_Code"VALUE="yogamat">
Type the Product Code of your Product.

<INPUT TYPE="text" NAME="Quantity" VALUE="1" SIZE="3">
This allows the customer to enter a quantity value for this product.

<INPUT TYPE="submit" VALUE="Add To Basket">
This creates the submit button. You can change the VALUE setting to anything you like, that text will appear on the face of the button.
