I am assuming you have a field on your form with a drop down list and that your values are something along these lines:
1; Option 1
2; Option 3
3; Option 4
The email will have the value of whatever value eventually gets stored in the database for that form. So in this case it would send out 1, 2, or 3, and you want to get the text values, correct?
The only way I can think of would be to create a custom macro and pass in the value and look up which option it is.
