Multiple values to variables in sp

[Rider]

hi
i want to know how to assign different values to variables on different touches.
(Eg):If box A touches box B then a variable,say "Rider" is given value of 1.
When box A touches box B the second time,"Rider" is set to value 2 and so on till the final value,say 10 is reached(i.e till box B is touched 10 times and till "Rider"==10)
please tell me if anyone knows .
