2 Drop down lists depending on 1 other drop down list.

Hi there .My problem is that I want 2 drop down lists to deppend on the same drop down list. I know how to make a drop down list via validation and a second drop list deppending on the first and so on. But how can I have 2 dropp lists depent on 1.

Drop list A has clothing (t-shirt,polo,jackets)
Drop list B has clothin codes for each type of clothing

So when I choose from list A i have the specified codes from list B.
So far I dont have a problem.
My problem is I need a Drop list C with colors that will be the same for all item codes of each type

So ALL t-shirts have the same list of collors. ALL polos a diferent list of collors and so on

That means LIST B and LIST C deppending on LIST A
Any good advises for it

TY in advance and sorry for my poor english I hoppe I am clear about my problem.

Hi .Γειά σου Πατρίδα!

Why don't you use the same way that you used for making a depanted validation list in column B, also in column C?

Ok. My head is too heavy now for such a work. Take a look to this and this.
