API error message: Some fields are missing.

joomladirect

I am combining the Sendy name and email fields with another form on my site, and doing a silent post to my sendy/subscribe url. The form is filled out but submitting returns the error message from sendy "Some Fields are Missing"
These are the fields I am using in the form:

input type="text" name="name"

input type="text" name="email"

Any idea what the problem might be?

Sendy is not receiving your email or the list's ID POST'ed from your script. Verify that your code is doing a POST correctly to Sendy and that both email and the list's ID has been POST'ed to Sendy's subscribe URL.
