# --description--
The `locations` array contains two locations: the town square and the store. Currently you are passing that entire array into the update functions. Pass in only the first element of the `locations` array by adding `[0]` at the end of the variable. For example: `myFunction(arg[0]);`.
The `locations` array contains two locations: the `town square` and the `store`. Currently you are passing that entire array into the `update` function. Pass in only the first element of the `locations` array by adding `[0]` at the end of the variable. For example: `myFunction(arg[0]);`.
This is called <dfn>bracket notation</dfn>. Values in an array are accessed by index. Indices are numerical values and start at 0 - this is called zero-based indexing. `arg[0]` would be the first element in the `arg` array.
