Be careful using random numbers in multiplayer, each client will come up with a different result. See multiplayer tutorials for more general information about locality.
The number returned is unlikely to be a whole number.
To return a whole number use either ceil or floor together with random.

x=floor(random 5) will return 0,1,2,3 or 4. x=ceil(random 5) will return 0, 1,2,3,4 or 5. (0 is unlikely, but possible, as ceil 0 is 0)

You can also use round with random to create whole numbers, if you don't want to exclude the high or low numbers, as will happen with ceil and floor.
