Tiny Javascript Task - Help!

I want a small javascript code to generate a random numbers based on some inputs, and show these numbers on a webpage so that it looks like the number is changing. Basically, these numbers are the value of a jackpot on my website. I want the jackpot value to be increasing so that as the user looks at it, the jackpot increases randomly. What I want to do is give a starting value to the javascript (eg. 100.30) and and then a series of values to randomly add to the value every X seconds. E.G. Starting value: 100.30 Random values: 0.01, 0.02, 0.03 Seconds: 5 In the example above, the javascript would choose one of the 3 values between 0.01 and 0.03 every 5 seconds, and add it to the starting value of 100.30, so that the variable could increase like: 100.30, 100.31, 100.34, 100.37, 100.38, 100.40... and so on. Note, that some of the random values I specify could be negative or 0. What I also want is a maximum value so that once the variable hits a certain value, it resets back to the starting value. For example, let's say the maximum value is 100.40, then the next value in the series above would be 100.30 because it resets. Each random value to add should be given equal weighting, so by including the value 0.01 twice, for instance, it should on average appear twice. I was hoping to use normal text for the changing variable, but I understand from chatting to coders that I may have to use an textbox in a form so that the variable can change?
