formula problem w/ conditional formatting

hi guys,
need help for this problem, can someone help me to make formula in conditional formatting.
i try to make this but it work only in separate cells =IF(G4>125,0,1) & =IF(G4>125,ROUNDUP(G4/250,0),0).
but not in formula for conditional formatting.

in simple ways:
less than 125 device, maximum 1219 meters (more than 1219 it turn red)
between 126 up to 175 , maximum of 762 meters (more than 762 it turn red)

thanks!
