Spaces are used to separate different arguments in a command. The way that Minecraft will be trying to parse your command currently is:

Command:        /effect
Player:         @a[x=0,
Effect:         y=0,
Seconds:        z=0,
Amplifier:      r=0]
HideParticles:  4
?               10
?               3

The first error it notices is that @a[x=0 is an invalid selector/name, so it gives the error message "The entity UUID provided is in an invalid format".

To fix your command, you should remove the spaces after the commas in the selector. Try this command:

/effect @a[x=0,y=0,z=0,r=0] 4 10 3

Range 2 is the range a player want for a command block under a floor. Keep in mind that it will produce a globe shaped trigger area (rather than a cube), so a range of 2 makes an approximately 5\xd75\xd75 area and a range of 1 makes a 3\xd73\xd73 area (more like a + pattern with an extra block above and below the center).
