thanks for the replies. i'll try them when i go to work in a few minutes. i've only been using labview for two weeks, so i don't know all the basics yet. i think i remember trying to put the subVI outside the sequence structure and have inputs from within the structure and it didn't work right, but maybe i didn't do it right.

i'm working on a flow injection program that controls some valves and reads measurements from an instrument. the part that reads and graphs the measurements is in a subVI. currently this subVI is in a sequence structure because i need to execute some things before it is called. when the program gets to the frame with the subVI, it calls the subVI and waits for the subVI to finish before going to the next frame. the frames after control the timing of the valves, so they need to execute while the subVI is running. is there a way to make the sequence progress when the subVI is called instead of waiting for the subVI to end? if no one can help without looking at the VI, i'll post it tomorrow afternoon when i'll be back at work.
