sorting values
hello world
im having trouble sorting some values
i got the inches to be sorted and now i need to sort the dates to go with that value
if the input is:
december 12 == 14
december 13 == 7
i need it to switch like this
december 13 == 7
december 12 == 14
instead of
december 12 == 7
december 13 == 14
