Dynamically number of parameters

I have 3 paramemters. How i can dynamically show/hide other two parameter based on the value as 1 or 2 input from the user from the first parameter? (for example: if the user enter 1, i will show the second parameter, if tyhe user enter 2, i will sho the thirs parameter on the report so the user can enter other value in these dynamical parameters?)Thats not possible. What is possible to still display them , but to clean them to show no value. That can be done using a query in the parameter definition.
