Using control variables gets a little messy because of the relationship of the rb matrix. They are arranged in a 4 X 4 matrix where each column is grouped (via intVars) so that no more than 1 rb per column can be selected, but each row makes up the 'status' on one 'item' so any combination of buttons in a row is acceptable. One solution I have been contemplating requires setting the value of each rb to the row number ( 0, 1, 2, or 3 or 1,2,3, or 4 in case I need to use 0 for 'none selected'), and using one intVar for each column. Then I would have to loop through all four intVars four times to determine which radiobuttons are selected in each row. That's what I mean by messy.
