Can PBP understand negative numbers?

PumpMath = (Throttle - ThrottleMin) * 100 / RadioScalefactor

if (PumpMath > 101) or (PumpMath < 0) then
PumpMath=0
endif

if (CurrentStep + 1 < PumpMath) and (PumpMath < 100) Then
IF (CurrentStep < PumpMath) Then
CurrentStep = CurrentStep + 1
EndIF

IF (CurrentStep > PumpMath) Then
CurrentStep = CurrentStep - 1
EndIF
endif

if (CurrentStep - 1 > PumpMath) and (PumpMath >0) Then
IF (CurrentStep < PumpMath) Then
CurrentStep = CurrentStep + 1
EndIF

IF (CurrentStep > PumpMath) Then
CurrentStep = CurrentStep - 1
EndIF
endif

THANKS! I think I figured it out!
