Hi

I need some help with the following.
I have a checkbox when checked reveals hidden rows.

Now I would like when the same checkbox is checked that it would also populate multiple cells in a single column with various numbers. and when it is unselected the cells go back to value of 0.

Ex. Checked, Cell E2 = 4, E3 = 1, E4 = 2, etc etc.
Ex. Unchecked, all previous cells = 0

Thank you,
