You can try creating additional custom items in your questionnaire with the additional HTML form variable names you want to keep. If you do not include a filename for the items, then MediaLab will know they are just placeholders for additional variables. See this discussion thread on the Empirisoft support forum for an example using custom items that have multiple variables that use radio buttons, similar to your files: http://www.empirisoft.com/support/sh...t=custom+radio
