OK, I guess your problems is with programming in general.
"answer.variables[0]" means:
1. Get the value of the "answer" variable,
2. and within that value, take the value of the item called "variables"
(and there it fails, as it there is no such item inside the "answer"
variable),
3. and within that value, take the first item (you actually never
reach this step)
What you wanted is certainly "answer[variables[0]]", which means:
1. Get the value of the "answer" variable,
2. and within that value, take the value of the item whose
name is deduced as follows:
2.1: Take the value of the "variables" variable
2.3: and within that value, take the first item.
