Need Help getting a index using another index

Apologies if this sounds silly.

I’m using a Hierarchy of Data types so I can search for certain things, I got three Data types that has a code and a description, and I want to use a dropdown that let’s you choose between each Data Type and another dropdown that let’s you choose one of the codes inside said Data Type, however, I want to show the description of this Code in a text.

Is it possible, or am I causing myself too much trouble with something impossible or too complex?

Sure it’s possible

Just using a workflow [when a thing is changed] have it do a search for the text, using the drop downs, then display a group containing that text.

If this is confusing try it out and DM me your editor and I’ll see if I can help

So I need two groups, one for the Dropdown that will look what value the other dropdown is, and another for the text that shows the description of the first dropdown?

Yeah, that’s one way to do it. You might not need a workflow if the group can reference [dropdownB’s item] then the text can be the parent group’s description

Using two groups doesn’t seen to work well.

I got a Workflow [When an input value is changed] that has [When Dropdown B is changed and this dropdown’s value is A], which action(s) should I use so it can display only the data that Value A should be?
