I can not connect the waveform information output of ni-scope multifetch function, it shows an error "These cannot be wired together because their data types (numeric, string, array, cluster, etc.) do not match. Show the Context Help window to see what data type is required. The type of the source is 1-D array of cluster of 8 elements. The type of the sink is cluster of 8 elements.",How can its e.g. actual sample be extracted?
