I have an array named a_array with the following:

(1,1) = "ANA"

(1,2) = "38LD0HDN-38L1D0HDR"

(1,3) = "2010-08-24"

(2,1) = "ANA"

(2,2) = "38LD0HHV-38L1D0HHZ"

(2,3) = "2010-08-24"

(3,1) = "ANA"

(3,2) = "38LD0HI3-38L1D0HI7"

(3,3) = "2011-07-23"

I need to sort the array by the date in descending order, but it keeps on giving me a data type error when I use asort(a_array,3,-1,1)
