I'm new to DLL's. I want to create a DLL using Labview which outputs an array. I built a VI that outputs an array...how do I turn it into a DLL

I built a labview VI  that takes two controls and adds then and puts the result in a indicator..the dll works fine....when I try to build a dll with an array as the output I cant seem to get it to function.....

Maybe I'm missing some steps for the array case.....
