Assigning a radius parameter to an array

[mframpton20]

This is a bolt hole radial array for a plate I'm working on.

I've managed to program the diameter of the holes and can produce the qty of holes as a parameter.

Now I'm stuck on how to assign a radius parameter to the center of the array. Thoughts?

TIA

Found the solution. The secondary vertical dimension when activated can be flipped into a parameter you have created.
