I was woundering if their is a such html code that I input a value (say 1000) and ti automatically adds 5% to it every say 30 minutes? Is their a such script?

Like if someone said the number 1000 on the website, and locked in the value. They need to get 10% every 30 minutes. Is taht possible?

here's a jQuery solution:

Since you didn't specify, this example will add 10% of the entered value exponentially to the total value. Ie, every 3 seconds it will take 10% of the total and add it to the toal. Then 3 seconds later it will find 10% of the new total and ad it to it and so on.

Should be pretty straight forward as I added comments to the JS by the areas that need to be changes to suit your needs.
