RE: question about table elements

[jdarling@...]

Below are two solutions to your question, the code that you posted asks
for t2['tmp'] when you want t2[tmp]:

t1 = {
  ["a"] = 1,
  ["b"] = 2,
  ["c"] = 3,
}

t2 = {
  ["x"] = "a",
}

tmp = t2.x
print(tmp)     --> a
print(t1[tmp])  --> a
print(t1[t2.x])  --> a
