In Business Rules, How to create a loop with counter?

I am using a rule to create a record in a table. I want to create more than one record, and want to have a loop that runs dependent on a value provided in a webform Qty field. I can see Loops for views and others, but I don’t understand how to create a loop (x) or if /then statement. Can someone gin up an example or describe a method I can use?
