Cannot add array item to 1D array

[kennethone]

Good afternoon,

This is for Teststand 4.2

I have a LabView module in my sequence which takes a 1D array of "parameters" and outputs a 1D array of "results". The problem is I cannot add an Array item to Parameters, but I can add an array item to Results without a problem.

It seems obvous that this may be because parameters is an input, and results is an output. 

But next to this module,I have another (imported by a different developer), calling the same exact VI that allows parameters to be added to the array.

Can somebody help explain why this occurs and what I am missing? 

Thanks.

Uncheck the "Default" for your input.
