Custom payment form does not to go PayPal for processing upon submission

Custom payment form does not to go PayPal for processing upon submission

In Zoho Sites I've built a custom payment form and have provided my PayPal email for the PayPal account. Upon form submission the form does not direct to PayPal. The form stays on the web page. Anyone gotten a custom payment form to work and go to PayPal? Should I assume form builder in Sites cannot build a custom PayPal payment form?

I should add that the form data is collected and I can see the form submission results. I'm just not getting the direction to PayPal after form submission.

Should also mention that I have a paid Zoho Sites Pro account is that matters.

I also noticed. If I add a PayPal button widget:

target="paypal"
action="https://www.paypal.com/cgi-bin/webscr"


In the custom payment form

action="/siteforms/addRecordValidate.do"
there is no target

Does the addRecordValidate.do perform the redirect to PayPal?
