I guess what you looking for is 100 + Random(100). It is going to pick a random number from range 100-200.

The reason you need to do it this way because Random(100) pick a number from range 0-100.
When you use the Random() expression, 0 is always included regardless how high the number is. If you do Random(1000) it is going to pick a number from range 0-1000.
To set a range of 500-1000 for example, you need to do 500 + Random(500).
