Lua - direct package path to another folder in parent director

I have a directory laid out :

-parent
    -target
    -current
        -firstChild
            -secondChild

I am trying to direct my package.path from inside "secondChild" to "target" to retrieve other .lua folders stashed there. I have this set up currently

package.path = package.path .. ';../?.lua;../?.lua;../?.lua;target/?.lua'

That doesn't find what I'm looking for and I'm sure that part of my problem is that I do not understand all of the syntaxes. ";../?.lua" says, to me, that I am dropping back to "firstChild" and checking to see if there are lua files?

What am I missing here?

Given your (updated) directory structure you need to have ../../../target/?.lua in package.path to reference modules in target folder from secondChild. ?.lua will search in secondChild, ../?.lua will search in firstChild, ../../?.lua will search in current, ../../../?.lua will search in parent and ../../../target/?.lua will search in target (assuming your current directory is secondChild when you start your script and also assuming that - is not part of the directory name). Having ../?.lua only makes the search to happen in the parent of secondChild and having target/?.lua makes the search to happen in secondChild/target/ folder, which doesn't exist.

The error message you get when you try to "require" a module includes all the paths that have been checked by the search, which usually provides a clue as to how the search path should be modified.
