Dynamically populate dropdown list

[android1]

Hi,

I have a 2 dropdown lists.
The second dropdown is (dynamically) populated depending on what is selected in the first (using =INDIRECT).


The second dropdown list gets it's source data from 6 columns. The number of rows varies in each column.
The first dropdown list gets it's data from these column headers.

My problem is:

The second dropdown list will not populate because the number of rows varies in each column.
(I have had to add random data in each column so the row total match)

How can I remove the random data so that dropdown 2 will populate correctly.

In attached file - Col C = Dropdown List 1, Col D = Dropdown List 2

Col D data source = Col T:Y

How can dropdown 2 populate if I remove the random data (z) from the 6 column T:Y

There's no need for all those zs, it works for me without them.
However the DV formula in D2 should be
=INDIRECT(SUBSTITUTE(C2," ","_"))
and you will need to remove the trailing spaces from some of the cells in T1:Y1
