C# index problem

Hello,

I am working on developing a C# node. Using random inputs, we are creating some nested for loops to create lofted circles. Unfortunately the nested loops are not working. For some reason, the p counter variable on the inner loop is not reading. However, if we replace the p with the number "1" it works. So there is something wrong with the loop or the naming of the variable? Really not sure. Any ideas?

Thanks,

Ben
