The SendLetter properties palette should now look similar to this:

With the component configured, the remainder of the form must
be created using Fusion's form tools. It is critical that these additional fields are named correctly and present in the form if you have selected 'required' in the admin for that field. Correct
names for the form fields are:
- Contact_email - this is required in every SendLetter form
- Contact_firstname
- Contact_lastname
- Contact_fieldname
NOTE:
1) The names above apply to the name value entered in the form properties box as shown below.
2) Be sure to enter the names as shown. No spaces in between the words, only an underscore.
Adding the Contact_email Field
The Contact_email field must be included in every SendLetter form. Select the 'Forms Edit Field' tool from the Forms Toolbar
and place a Form Field on the page.
With the Forms Field
selected enter Contact_email as the field name in the properties palette. Adjust the visible and maximum length to suit your needs.
With the Contact_email
field added, continue to add other fields as you have specified in the SendLetter online admin area.
NOTE: Regardless of how you present the optional 'Other' field
to the site visitor, the field name in the form must always be Contact_fieldname
POWER TIP: Having trouble with the alignment of your form
elements in the generated page? Lay out your form in a table. This will help to display the form as you intended.

Creating Success and Failure Pages
If you have set the Success and Failure URLs to YES in the
SendLetter admin area then you will need to create these pages and place them on the server at the URL you have specified. This can be done as part of your Fusion site. The site visitor will
see the Success URL when the SendLetter form has been successfully submitted, the Failure URL if there has been a problem - e.g. a required field has not been completed.
NOTE: The Success and Failure URLs must be absolute URLS beginning with "http:".
SendLetter Form TroubleShooting!
With your site published to the server you are ready to test
your SendLetter form. If you receive an error message from the services.coolmaps.com server it means you have an error in the form. Check the form source. Ignoring all of the other code, the
form code should look similar to the code below (with your own values inserted).
<FORM NAME="LAYOUTFORM" ACTION= "http://services.coolmaps.com/sendletter/router.cfm"
METHOD=POST>
<INPUT TYPE="HIDDEN" NAME="contact_listID" VALUE="YOUR VALUE" >
<INPUT TYPE="HIDDEN" NAME="contact_listCode" VALUE="YOUR VALUE" >
<INPUT TYPE=TEXT NAME="Contact_email" VALUE="" SIZE=12>
<INPUT TYPE=TEXT NAME="Contact_firstname" VALUE="" SIZE=12>
<INPUT TYPE=TEXT NAME="Contact_lastname" VALUE="" SIZE=12>
<INPUT TYPE=TEXT NAME="Contact_fieldname" VALUE="" SIZE=12>
<INPUT TYPE="submit" Value="Subscribe to Mail">
</FORM>
