Title: MTA and calc

The **MTA** works:
+ Forwards for multiline trips
+ Forwards for trips that don't pass Union Square
+ Forwards then backwards for multiline trips

But not for:
+ Forwards for trips that pass Union Square on the same line

I get a bad range error. I think it's line 11 - 13 not handling the indexes right?

I also wanted it to get the line automatically from the stop by finding the key from the item inside the value's array. Joel said to use a loop.

The **calculator** I wanted to quit and check for response from any menu:
+ It works only when you ask for which calculator you want to use
