Mandatory Fields

Mandatory Fields

I was wondering if anyone could help me.  I have a few forms on our site that use the Zoho CRM and I love everything about the CRM except I can't seem to figure out how to do mandatory fields. 

We are getting some submissions that are not complete (Like on Leads, Accounts Contacts and Trips) and we have to have this capability to ensure the forms are filled out correctly. These incomplete entries are then providing incorrect stats when I pull them through Zoho Reports

Is there a way to do this?  I don't want to have to go to a different CRM because it offers everything else I am looking for. I am fairly new to Zoho CRM so if you can, please may I have the response less complex

Please let me know if there is a way to do this.

Thanks so much!
