Hide/Unhide rows and column based on cell value

HI, I need your assistance with the following:

When this Excel form is being filled out, columns H through M will be hidden and rows 9 through 21 will be hidden

Here's what I need help with: (note: cells G5 and I5 are drop downs with Yes and No answers)

If the user selects YES (cell G5), I need only rows G9:G21 to unhide
If the user selects NO (cell G5), I need columns H and I to unhide, BUT rows I9:I21 to stay hidden

THEN
If the user selects YES (cell I5), I need rows I9:I21 to unhide
If the user selects NO (cell I5), I need columns J through M to unhide

Please Note: if I picked YES in cell G5 or I5 (by mistake), and then chose NO, I need Excel to toggle/revert back and hide rows G9:G21 (or I9:I21) once NO is picked

Please see attached sample file.

Any help is greatly appreciated! THANKS SO MUCH IN ADVANCE!
