I want to create a multi data valdation

Right now the user selets from a drop down list in Col 1 which then gives the user a drop down list to select from in Col 2 based off of their choice in Col 1. I need to create another drop down list in col 3 that is also based on the col1 but is different data than col 2 offers. Is this possible? Right now my Col 3 just shows the same options from col 2.

COl 2 is Indirect(a1) same with col3. Do I need to do a different type of indirect of vlookup?

Any help would be great thanks.
