To compare the values of two columns, click the Compare column check box. Select from the list of columns for comparison.
Click an option under Current Selection to tell JMP how to handle that current selection:
Clear removes the highlight from currently selected rows and selects all rows that contain the specified value.
Extend keeps the currently selected rows selected and also selects the rows in which the specified value has been found.
Restrict selects the rows in the currently selected array that contain the specified values.
Click Add Condition to add a condition to the list.
To add more conditions to the search, repeat the previous steps. Click the appropriate item in the Select Rows area to specify if you would like JMP to select rows conditionally: if all conditions are met, or if any of the conditions are met.
To keep the window open after you click OK, select Keep dialog open.
