How to clear dependent drop down list when value in parent cell is changed

[Sumit_Vikram]

I have dependent dropdown in column "H" (row 8-44). Cells of column "I" is dependent on cells of column "H" and that of "J" is dependent on "I". I want to clear the values in cells of column "I" and "J" whenever I change the drop down selection in cells of column "H". I want to do this to all the cells of column "H" from row 8-34. Can anyone help me with the VBA code. I am new to VBA and don't have much idea around it.

Thanks
