I have gotten a main VI that will pull in several sub-VI's to do some testing. I want the main VI to not just pull in the cluster information that the sub-VI has, but also what kind of information. For example, in one of my sub-VI's, I have a cluster which contains age, height, weight, and size. I want my main VI to automatically create the same cluster after open the sub-VI. In another word, the main VI will make an exact copy of the cluster in the sub-VI and put this cluster in its front panel. Do you know how to do this? Thanks.
