rand generates a random number betweeen 0 and 1 e.g. 0.2386234 or
whatever. If typing rand on its own from the home screen is giving
you an errror then it may need a seed - try typing "0->rand" (where ->
is the sto button).

I which case type:
iPart (rand*10) +1
basically take your number, multiply it by 10 and take only the whole
number part. On its own this would give you either 0,1,2,3,4,5,6,7,8
or 9 - but as you wanted 1 to 10 (not 0 to 9) simply add 1.

Simply take the line above and store it (->) into a variable.
I hope this helps, if you have any questions just ask.
