Then your Prompt User function runs just once, and puts up the dialog box and waits for the user. So your timeout function executes just once, and passes it's result to the Or function. See, at the start of a pass through the program diagram, in particular the first execution of your structure, both the Timeout function and the prompt user function can begin executing right away, because they have no inputs on the block diagram. Case Structure or loop), then in point of fact your Timeout function would only execute once! In fact, if the Prompt User function, Or Function, and Timeout function are in the same Structure (i.e. One might think that since the timeout function could eventually return a true, that the Or function would be able to short-circuit evaluate the result, since the second input would not make a difference to the output of the Or function, so LabVIEW could just move on. This is what LabVIEW means when they say that it is a dataflow language. Since it never returns any values, the Or function that takes that value as input can never run, because it never gets an input value. The Prompt User VI is halting - in that it's node on the block diagram doesn't return any values until the prompt is done. Do not be ungrateful or condescending/patronizing.When asking specific details concerning your project/problem, please provide adaquate means of information, as screencaps, flow-charts, etc.
