CMS Made Simple Forums

Hi all,
i have a formbuilder (Ver. 0.4.4 on 1.2.3 Black Rock CMS) form with a sendto field.  The sendto field is valorized with an internet address.
In the "Advanced settings" I have created a text email template:

Date submission: {$sub_date};
Remote IP address: {$sub_source_ip};

Mail sent to          {$fld_xxx}
-------------------------------------------------

*Message________________: {$fld_yyy}
ecc. ecc.

When submitting the form, the email is correctly sent to destination but the {$fld_xxx} value is not set and a [-] symbol appears.
I tried also with {$sendto} instead of {$fld_xxx} but the behaviour is the same.

Please help me, I need that information in the email.

Thanks and Best Regards. 

any solution??
