What do you mean by "array containing global variables"? I don't know of a way to create an array that contains globals. You can create a global that has an array of numbers, strings, clusters, etc. You index the array global in a VI just like you index any other array. You just have to make sure the global is set to read (right click and select Change to Read). If that's not the problem, could you post the global and the VI you've written to read it?
