Total members of the chosen clubs

The table clubs holds the members of three clubs in January and February. Put a multiselect widget (st.sidebar.multiselect) labeled Club in the sidebar. Its choices are Photo, Band, and Chess, and all three are chosen at the start.

Store only the rows of the chosen clubs in view. If nothing is chosen, show st.warning("Pick at least one club.") and stop with st.stop(). If rows remain, show the total members in a metric labeled Members.
