Sorting Macro

I'm attempted to create a macro to auto sort which i've managed to create but now would like to have it automatically run the sorting macro when certain cells values are changed..

the information I want sorted is in the following range O13:Y16
and would like it to auto sort when values are entered into the following ranges
H11:H16 and J11:J16

would like it to auto sort first by Pts (column X) then by GD (blended in column Y) then by GF (column U)
would like it to also work with the other group standings but one step at a time lol

thanks
