LIB FSC for arrays of Data Structures

Hello, A little background. I am using Metcal to calibrate barometers and I have a procedure that does a verification run on the barometers. Each barometer has between 1 and 4 cells (think of a cell as an individual sensor) each cell has 8 adjustment points and each adjustment point is a data pair of pressure and correction. <--break-> What I am trying to do I have been playing with the LIB FSC to try and build an array to store a series of adjustment points that are pressure and correction pairs. Using the LIB FSC I can create a data structure that is a pressure and correction pair. LIB STRUCT structure { Press, Corr }; LIB STRUCT NEW corrections OF structure; This works and I can read and write to "corrections.Press" and "corrections.Corr" Using the LIB FSC I can create an array I can create an array of single values. LIB ARRAY NEW Points[8] This works, I can read and write to the array. But if I try to create an array of the data structure. LIB STRUCT structure { Press, Corr }; LIB STRUCT NEW corrections OF structure; LIB ARRAY NEW Points[8] OF structure; Metcal is happy until I try to write a value to the array and then it throws a System.NullReferenceException error I am testing all this in MetCal Editor at the moment. Has anyone used the LIB FSC for Arrays of data structures? Does anyone know what my problem might be? Dallas
