When you create the form, add an input tag of type "hidden" with a value assigned to something unique such as "offer123" and then create a segment which has a demographic containing this information. You can generate a report and view all customers connected to that segment.
1. Add the input tag to the form with type="hidden" and value="<something unique here>"
Example:
<input type="hidden" value="offer123" class="form-input-text" id="scruggle" name="31570" />
2. Remove the field label.
Example--change:
<td class="table-form-left">scruggle:</td>
to
<td class="table-form-left"></td>
You can also remove the field label completely.
