Repeat database inserts depending on select value

I have a data insert that I would like to repeat ‘X’ amount of times on either a daily (1) / Weekly (7) / Bi-weekly (14)
the quantity comes from a text input in the form and the other daily/week/bi-weekly comes from a select list.
I am guessing I would need to set a repeat up in the action sets for the amount of times.
But how would I add the frequency times eg plus 1 / 7 / 14 days
if anyone could point me in the right direction this would be great.

Thanks
