Build path with strings

Hi,
Is it possible to build the string below but to pass a string for one of the parts for example

local mystring = White01
script.Parent.White.[mystring].RootPart.Row.Value = 1

script.Parent.White.White01.RootPart.Row.Value = 1

Yes, but you would not need a dot before the opening bracket.

It will be neater if you put a period before the opening parenthesis. Keep up the good work!
