Dependent Drop Down lists reset

Hey guys,

I'm new here on the forum, so nice to be part of the family and I hope you guys will be able to help me out! Here is the topic:

I created a spreadsheet in which I've got 5 drop down lists, all dependent to each other. So depending on what I put in cell J2, solutions are going to pop up in cell K2, then solutions in cell L2 are dependent from J2&K2, etc... until N2 (see attached). Everything has been fine until now (I still have to rename the all matrix in tab 2 though...), but I got stuck when it comes to make this bad boy work a more efficient way.

In fact, what I would like my spreadsheet to do is to simply reset values in cells K2, L2, M2 and N2 to the first value in the drop down list when I change the value in J2. The point is that then, I can sort my data so the most common value I need is first in the drop down list and appears as soon as I change the value in J2.

Now I read that thread

which is sort of what I need. But I do not know how to adapt the code to my spreadsheet....

Thanks in advance
