[solved] Cannot index global variable?

[Tesselode]

I want to have multiple bullets, so I'm keeping track of them with an index. When I run this:
player_bullet_x[player_bullet_amount+1]=player_x

I get the following error:
main.lua:31: attempt to index global 'player_bullet_index' (a nil value)

How can I add an index to a global variable without LOVE throwing up?

you have to make a table and give it that name:

player_bullet_index = {}

In Lua, any undefined variables are nil, which you can't index.

Hold on a second; I made a typo. The variable it was complaining about was "player_bullet_x." But adding "player_bullet_x={}" to love.load fixed the problem. So thanks!
