I'm trying to do a regularized spline interpolation on some point data and keep getting error 010024. I have 3 layers; a boundaries layer, a specific boundary layer (a subset of the first layer and serves as my mask) and my point data layer. The point layer is joined to a spreadsheet and only matching records were kept for the join. My map scale is roughly 1:9,000,000 so the cell output size is 37500 m (close to the value suggested by Arcmap. All layers are in the same geodatabase and have the same coordinate system
Attached is a screenshot of my results window.
