To do this:

• Open contact-us.html
• Insert > Form > Form
• You will see a red outline within your page. This is the ‘form’ tag. All your form fields must be placed within this tag.
• Insert Form > Text field
• In the screen that opens up type ‘Name’ in the label field. Click OK
  
• Similarly create a field for ‘Email’ as well.
• Also create a field for ‘Message’. This will need to be a text area [Insert > Form > Text Area].
• Finally create a button [Insert > Form > Button]
  
• With this you have created the HTML required for the form. However, to make the form work and send you an email you will need to use a php or asp script depending on your web server. You can also use a free email form service.
