Excel/Excel data validation


I had Asked this question dated 12/2/13 for which I got a valid reply:

Col 1 has four enteries. Col 2 has dropdown for each of the four enteries. Upto this it is working fine. Now in col 3 I want to add further dropdown for the dropdown options of col 2. Please suggest the steps to it

Now in the Col 3 I want to put the data validation function again depending on the col 2 dropdown selection. Please suggest the steps

Using all the possible values for column 2 (I used 3 in this example, a, b, and c), put in a formula like this in the data validation for List:
in J1:J3 are the values for a, K1:K5 are the values for b, and L1:L4 are the values for c.
