I think there are several problems in your code.

First, an OPTION object has a VALUE property. Also, the carriage-return you want is not an HTML <br>, but rather an ASCII 13.

So your option constructor should be like this:

Response.Write "<option value='" & objRSt("email") & "'>" & objRSt("assign") & "</option>" & chr(13)

Then, you need to access your selected item. A SELECT object has a couple of properties you can use. I will give two examples of how to change PutEmail().

Since you are passing "this", you can use it as the object reference.

//IE 4.0+, Netscape 6.0+
document.form1.txtEmail.value = objThis.value;

//IE 3.02+, Netscape 2.0+
document.form1.txtEmail.value = objThis.options[objThis.selectedIndex].value;

The newer version is much simpler, but it doesn't work with older browsers.

Actually, I'm not sure about using single-quotes to enclose the VALUE text. You might have to use double quotes, as in:

Response.Write "<option value=""" & objRSt("email") & """>" & objRSt("assign") & "</option>" & chr(13)
