st: Tabulating data with multiple visits--simple question

Sorry for how simple this is. Having too many problems with it so far.
I have data with multiple visits by the same person and would like to summarize results by counting their id's only once. How do I tabulate it? Data looks like
ID visits clear1 1 01 2 0 1 3 11 4 11 5 12 1 02 2 13 1 0 4 1 04 2 1
When tabulating, I would like the frequency of "clear" to be 3 (corresponding to ID's 1,2, and 4) NOT 5, based on visits. Please help. Thanks!
