http://www.artesiagardens.com/htmls/test-contact.html is not even valid HTML.
I just ran it thru the HTML validator at w3.org: http://validator.w3.org/check?uri=ht...t-contact.html
I know exactly why FormMail will produce this error. It happens when the HTML form submits a field call "conditions" which does not have valid content.
The questions are:
The quickest way to solve this problem is to grab our sample form.
- why does your form submit a field called conditions?
- is the invalid HTML contained in your form somehow creating extra fields you're not aware of?
- are there other things on your server (for example, Server Side Includes) that are injecting a field call "conditions" into your form?
Check that it works OK.
Then modify the sample form one step at a time until it looks the way you want.
