You're not going to use any kind of For/Next loop at all in this. You simply keep track of the row you're in in a simple integer variable. Every time you click Submit, or whatever you're calling your button, you put the textbox values in the cells, then increment the variable to point it at the next row. Check the variable to see if it's gone too far and adjust as you see fit. Then, you do nothing... The whole process starts over again on the next button click.
