How to retrieve variable from parent table in Lua

Question

I have a table(TableA), that has another table in it(TableB). I want to retrieve a variable that is located in TableA from within TableB. How would I go about doing this? I have tried:

tableA = {
testA = 5;

    tableB = {
        testB = tableA.testA + 1; 
    };

}

print(tableA.tableB.testB)

but get an error from within tableB that states that tableA doesn't exist.

Answer 1

tableA.testA does not exist until the definition of tableA is complete.

You need to do tableA.tableB.testB = tableA.testA + 1 after tableA is complete.
