Hi All, I am writing a large program in LabVIEW and one aspect of it is a quiz-type structure. There are 4 possible answers to each question (a, b, c or d) which correspond to a cluster of 4 radio buttons. The quiz questions and answers are stored in an array. The array contains 5 columns; the first (0) contains the questions and columns 1-4 contain the four possible answers. The fifth column is a number corresponding to the correct answer i.e. 1=a, 2=b etc. In order to check if an answer is correct, when the user clicks the"NEXT" button, the radio buttons are read. If the answer is 'a', a '1' is output, if it is 'b' a '2' is output etc etc.This output is compared with the fifth column of the array and if the two match, TRUE is output, turning on an LED. However when I run my program it will not let me select an answer i.e. one of the radio buttons, even though I have them in a while loop. As the programme is much bigger than just this quiz aspect it is a bit large to post. I have included a screen shot below which may help (but also may confuse more!). Thanks!

From your diagram, I can see "Radio Buttons" is Indicator and not Control. To select an option you will have to make it Control. 🙂
