Question: I'm trying to pull a string from my URL in WordPress, and create a function around it in the functions file.

The URL is:

"<https://made-up-domain.com/?page_id=2/?variables=78685,66752>"

My PHP is:

```
$string = $_GET("variables");
echo $string;

```

So I'm trying to return "78685,66752". Nothing happens. Is the first question mark a problem? Or what am I doing incorrectly? Thanks!

Answer: 
`$_GET` should be in the form 

```
$string = $_GET["variables"]; 

```

and not 

```
$string = $_GET("variables");

```
$\_GET is not a function but an Array so correct way of reading it is 

`$string = $_GET['variables'];`

You are also creating the query string all wrong, you should be using 

```
?variables=123,456&page=1

```
