Sorry if this question is too noobish, but I'm having lots of trouble doing something I thought would be simple. I want to create loops that run successively, and are timed. The first loop will not run until a button is pressed. Once pressed one loop will run for a set time, then a second loop will run for a different time. A third loop will run for another set time. After this all happens the button can be pressed to start all over again. What i've done so far is create a flat sequence structure, and put each loop in successive frames. Inside the first I have a case structure which the start button sets to true. When true it runs the first loop. I don't know how to make that loop run for the time I want it to after the button is pressed. I've been messing with all the timing and wait functions, but I'm only confused more now. Any help would be great. Thanks.
