Have you created the Variant "type" Cluster and fed that into the Type terminal. The "type", in your case, will be the 17 items (booleans, ints, strings, etc.) that you expect to have converted. It should be a 1:1 match. The vi will then match your Variant data with your predefined "type" and produce the Cluster data output. If you creat a constant for this terminal and then drag in the 17 types, you should be ok.
Good luck with it, Doug
