Hello,

Before loading subscription form we are taking user basic information on another form and then we need to pass first_name, last_name and email to per-poulated in zoho subscription form. However, when we passing parameters in zoho subscription iframe URL it's not loading into subscription form.

&first_name=zarl&last_name=Mac&email=zarl_mac@gmail.com

Would anyone suggest what's wrong with this and how can I pass this information into zoho subscription?
