no entry in shadeform still send input name

[rulrich]

If no entry is made in the shadeform for model number then I want to send via form mail the input name. in this example...
Model Number 1: and then blank or perhaps NO Selection would print.
If something is typed in then form mail would be
Model Number 1: GT08945-01

It works fine if they type something into the shadeform but I get nothing if they don't. And if I use input type hidden I get duplicate info.
