Mathcad 3D Plot from "random" dataset

[H2power]

I would like to create a 3D surface plot from a data set of (x,y,z) data points. Help says, "you can create a surface plot from a set of x,y and z data points. Create a surface plot region and type the names of the x, y, and z vectors separated by commas into the placeholder." I think I tried this and I just get the error "the array must have more than 1 row or column." What am I missing?
The data points do not fit easily into a Matrix. I am using Mathcad 2000.

Thanks

I think you need to follow the instructions.

You are missing ()
