Reference Planes Are Overconstrained

[mbolinSTBLH]

Trying to add an instance parameter for the horizontal location of holes (instance parameter "Location of First Row of Holes") similarly to how I did for the vertical location but I get the "Reference Planes are overcontrained" error. I did not get this error for "Location of First Column of Holes" instance parameter, so I'm confused about why it's happening. Any ideas on how to fix it?

You have already defined that value/dimensions with the Hole Spacing Vertical and Length/Width as this value it the remainder so cannot be defined.

You either drive the Hole Position by "Spacing" or "Edge Distance" the other value would be a Reporting Parameter as it will give you a value defined by the other Parameter
