First drop down choice on Paynow button with price choices failes

<!-- @page { margin: 0.79in } P { margin-bottom: 0.08in } -->

I get this message

PayPal cannot process this transaction because of a problem with the seller's website. Please contact the seller directly to resolve this problem.

When I choose the first drop down option on my buy now button, the $50 option. But if I choose either the second, $100, or the third, $150 option things work fine.

I am testing in sandbox and here is the button code

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">

<input type="hidden" name="cmd" value="_s-xclick">

<input type="hidden" name="hosted_button_id" value="1084493">

<table>

<tr><td><input type="hidden" name="on0" value="Amount">Amount</td></tr><tr><td><select name="os0">

<option value="Fifty Five">Fifty five $50.00</option>

<option value="Hundred ten">Hundred ten $100.00</option>

<option value="Hundred seventy">Hundred seventy $150.00</option>

</select> </td></tr>

</table>

<input type="hidden" name="currency_code" value="USD">

<input type="image" src="https://www.sandbox.paypal.com/en_US/i/btn/btn_buynowCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">

</form>

Why would that be?

Thanks,
Chas

Change this line:

<option value="Fifty Five">

to look like this:

<option value="Fifty five">

Your code apparently has an upper case "F" but, the details stored on the PayPal Server is expecting a lower case "f".
