Variables in PayPal post

[colesc8]

The following code posts information to PayPal:
<td><form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="name@yourname.com">
<input type="hidden" name="item_name" value="Conference_Fee">
<input type="hidden" name="currency_code" value="GBP">
<input type="hidden" name="amount" value="#Form.totalCost#">
<input type="image" src="http://www.paypal.com/en_US/i/btn/x-click-but01.gif"
name="submit" alt="Make payments with PayPal - it's fast, free and secure!">
</form></td>
I have an input form that gathers information about the user and his
requirements which posts to an action page which genreates a total cost. The
code above is on the action page and I want to post the total cost to PayPal.
The line of code that I am enquiring about is the one below and I have a couple
of questions that I would really appreciate answers to if anyone has been here
before.
<input type="hidden" name="amount" value="#Form.totalCost#">
1) My variable on the action page is #totalCost# Is the syntax I have used
above correct?
2) Do I need to put Form. in front of the variable.
3) Have I got hold of the wrong end of the stick entirely?
Grateful for all help.

everything seems to be fine mate. Just remove the FORM. in front of the variable.

Thanks, Maneesh. Must be the first time I've nearly got something right!
