"Contact Listing Owner" sends email even if no entry are made
1. Open one listing and click "Contact Listing Form". Without making any entry, just hit "Send Inquiry". It sends email with empty details. Validation should have been there prompting the user to enter details into mandatory fields.
2. Now click again "Send Inquiry". You see blank small dialog.
How to validate the data entered, so that we mandate user to input main fields?
