I don’t think the Create Row block can run in a loop that quickly. I think you might need some delay or you might have to nest the Create Row blocks inside the “do” section (note that this will currently **not** work because of a known bug. See [Create row block not working well from yesterday](http://community.thunkable.com/t/create-row-block-not-working-well-from-yesterday/887050). Also see the link @maxb posted above.
