I have an issue and would like to know if someone can make me an example with and explaination. In my main program i have a subvi and in that subvi i have another subvi preforming a calculation. I need to bring the values of the subvi 2 layers up to the main program. I used the link below on another program which worked but I'm having issues doing it on the program with subvis 2 and 3 layers deep. I tried creating a reference then placing the reference on the main program but the values was not propagation upward to the main program. I do not have the file available to view on this forum.
