Why is my float setting itself to "-infinity" ? [SOLVED]

[Mulbin]

I'm having real trouble subtracting on float from another.  The process should be very simple, the float starts at a fixed value of 3000, then every second it should subtact the value of another float.  But as soon as the game starts instead of subtracting the value it just sets itself to negative infinity.

Any suggestions?

You could try adding a Float Clamp- and clamp the power reserve min at 0-

I've seen behavior like this if the calculation starts before the variable has been populated so it might be doing the subtract before the powerReserve variable is set?

That's it!  Thanks, working fine now I have clamped.
