One thing to keep in mind is that the arrays coming out of the sequency structure will not have any data in them until the entire sequence structure has completed execution.
If you need access to data from a sequence strucutre, while the the code is still running in the sequence structure, you'll need to make use of a local variable.
If you have a simple piece of code with just the sequence strcuture, the data you're trying to read and how you have it being passed from the strcuture and being read in the VI feel free to post it. That might present some better alternatives.
