error 1003 when using flat sequence

[jklai]

Hi,

i'm trying to manipulate varibles following a certain sequence. what i have done is to use a flat sequence structure to do as so shown in the picture. am i right in doing so?

i am able to run this vi when the vi is targeted to the computer. however when i have the vi targeted to the nxt, it gives me an error message shown in the picture. does anyone know how to resolve this?

thanks

NXT Module 2009 does not support sequence structs with multiple frames. Support for Stacked Sequences(but not flat) with multiple frames was added in to NXT Module 2010, as well as improvements to that error message you got. 😉

NXT Module comes with LabVIEW for LEGO Mindstorms and should also be available as a free addon to LabVIEW 2010. It looks like it hasn't actually been posted for download yet but we should have it up soon.

If upgrading isn't an option, I would suggest using two sequence structures and wiring them together (perhaps artificially) to force one to execute first.
