How to set keybind for primary and secondary weapons using mouse scroll wheel up

This solution WORKS with the new season 4 update and has been tested by myself and verified to work 100%

FROM MENU SELECT / MOUSE AND KEYBOARD / EDIT KEYBINDINGS

STEP 1,  SET CYCLE PRIMARY WEAPON TO MOUSE SCROLL WHEEL UP

STEP 2,  SET SECONDARY WEAPON TO MOUSE SCROLL WHEEL UP

( IGNORE DUPLICATE KEYBIND WARNING )

NOW START A GAME AND WHEN YOU NOW MOVE MOUSE WHEEL UP IT WILL SWITCH BETWEEN YOUR PRIMARY AND SECONDARY WEAPONS EACH TIME YOU MOVE THE MOUSE WHEEL UP

I hope this helps you guys and solves the same problem that I was having before I figured out a WORKING SOLUTION

Have fun guys
