The Checklist need to include the follows:

1. The user on Checklist insert parameters into a specific cells, whereas
all other
cells can't be marked, pointed or edited.

2. When the user insert a parameter and pressing Enter, the next
r-e-l-e-v-a-n-t
cell is pointed (the next cell the user need to insert parameter into).

3. Blank rows or columns, that are not a part of the Checklist, won't be
presented.

Note: The "protect sheet" option isn't providing me all of the above..

Thanks in advance!
