By default SoftCart will pass all information that it collects on the online order page. If you add a new field to your online order page called Address3:
<INPUT TYPE=”TEXT” NAME=”Address3″ Value=”” Size=30>
You will need to make a change to your order delivery templates to capture this information. The tag that you will need to add is <Field_Name>. In the example that we used above the tag would be <Address3>. These tags are case sensitive so you will need to verify the spelling of the field names.
