Hi William,
The button needs to be between the <form> </form> tags.
Find the block of code:
<p><span class="formItem"><span class="buttonFieldGroup">
<input class="formButton" name="Consult_submit" type="submit" id="Consult_submit" value="Submit Consultation Form" onclick="clearAllServerErrors('Consult_Brassy_CSIForm')" tabindex="18" />
</span></span></p>
and cut and paste it just before the closing </form> tag. Then remove the '<span class="formItem"> and </span>' (coloured blue) from that pasted block of code.
The button should now appear in your form.
You may also want to remove the left margin from the form.Brassy_CSIForm input.formButton rule at line 191 of your webassist/forms/fd_brassy_csiform.css stylesheet:
form.Brassy_CSIForm input.formButton {
margin: 0; /* changed from 0 0 0 50px */
padding: 0;
}
