I do not know if you have noticed this but the developer stopped working on this quite some time ago. But if you create a small html form and then paste the WP tag into a text widget it will work fine. This is what I use…
<p style="margin-top: -40px; text-align: center;">
<span style="font-family: Times New Roman, Georgia, Serif; text-align: center; color: #0000ff; font-size: 14pt; font-weight:bold;">CONTACT US TODAY</span>
<center>Please fill out this short form and we will contact you immediately...</center>
</p>
<p style="text-align: left;">
<font style="color:red;">*</font> <font style="font-weight: bold;"><label for="your-name">Your Name...</label></font></p>
<p style="margin-top: -20px; text-align: center; ">
[text* your-name 25/]
</p>
<p style="margin-top: -20px; text-align: left;">
<font style="color:red;">*</font> <font style="font-weight: bold;"><label for="your-email">eMail Address</label></font>
</p>
<p style="margin-top: -20px; text-align: center;">
[email your-email 25/]
</p>
<p style="margin-top: -20px; text-align: left;">
<font style="font-weight: bold;">Telephone...</font>
</p>
<p style="margin-top: -20px; text-align: center;">
[text primary-phone 25/]
</p>
<p style="margin-top: -20px; text-align: left;">
<font style="font-weight: bold;"><label for="your-subject">Legal Matter...</label></font>
</p>
<p style="margin-top: -20px; text-align: center;">
[text your-subject 25/]
</p>
<p style="text-align: right;">[submit "Send"]</p>
