Hi Austin, I can't view your control (haven't switched to 2011 yet). It should of course, be a type definition. Attached is an example of a technique I use when dealing with arrays of clusters. In essence, you just: Work with one element of the array at a time. Change one cluster item while maintaining the value of the other cluster items. Replace the array element. I hope this gives you some ideas on how to implement your requirements. steve Array of Clusters.vi Control 1.ctl
