You're trying to access an invalid index from a container-type variable(List/Array/Hashtable). Either the 'container' isn't initialized or you're reaching for a non-int, or a negative int. In any case, the problem is you're calling an inexistant value.

or you are trying to go above the bounds of the array itself. Array of 5 objects but your trying to read index 10 for example.

People often have an off-by-one error. $$anonymous$$ind that an array has a range starting with 0. So an array of 3 has index: 0,1,2. 3 is already OutOfBounds.

Without seeing the code that produces this error, there's nothing else to add ;)
