MW2 G-Walk Razer Macro

I'm actually having such a hard time figuring out how to make a proper g-walk macro for anyone that doesnt know its a way to walk full speed while kinda half crouching. someone told me to do something like

Prone Press
Prone Release
+ 50ms Delay
Sprint Press
+ 50ms Delay
Sprint Release
+ 300ms Delay
Repeat while holding Q

but doesnt seem to work if anyone has something that works lemme know
