Array sort question

Hi, How can I sort a 2 dimensional array by number of elements? Ex: rgArray[0] = ("1","2"); rgArray[1] = ("1"); rgArray[2] = ("1","2","3","4"); rgArray[3] = ("1","2","3"); Now I would like to sort it so I can loop through them from least elements to most (or vice versa): rgArray[1] (now rgArray[0]) 1 rgArray[0] (now rgArray[1]) 1,2 rgArray[3] (now rgArray[2]) 1,2,3 rgArray[2] (now rgArray[3]) 1,2,3,4 Thanks.
