The only action I'd add to @Georg 's recommendation is since the design may have originated in a non JMP application I'd spend just a few minutes examining each column's column properties dialogue to insure the data type and modeling type for each column are as desired. Last thing you want is a numeric/continuous column being treated as something else or any other undesired combination. JMP relies on these column property specifications for LOTS of behind the scenes analysis/visualization/workflow actions.
