I have a 2D Array. If I do `print_r($equities[0])` , I get:

```
Array
(
    [No.] => 1
    ["Ticker"] => "CAFE"
    ["Company"] => "iPath Pure Beta Coffee ETN"
    ["Price"] => 27.59
)

```

I then try to print the 'Ticker' for the first element like this:

```
echo $equities[0]["Ticker"];

```

But, it does not print anything. How can I print the ticker?
