I am trying to test the following code in paypal sandbox environment but it is returning an error. Below is the code that I plug into the button script.
<form target="paypal" action="https://www.sandbox.paypal.com/*********" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="***********">
<table>
<tr><td><input type="hidden" name="on0" value="Name of drop-down menu">Select A Date:</td></tr><tr><td><select name="os0">
<option value="$25.00">Saturday August 15, 2015</option>
<option value="$25.00">Saturday August 29, 2015</option>
</select> </td></tr>
This is the error message "PayPal cannot process this transaction because of a problem with the seller's website. Please contact the seller directly to resolve this problem."
On the checkout page I should see the selected option and the value which is the cost but I am not seeing anything in the sandbox.
Could someone please help me to solve this problem?
