Dynamically Populating Field with Variable through a PHP Embed

Hi, I just upgraded my license to developer and am finding more and more great uses for Gravity Forms every day. Thanks for doing great work :)

I'm having some difficulty using a PHP variable to dynamically populate a field. When I use this code:
```
add_filter("gform_field_value_jobname", "jobname");
	function jobname($value){
         return "test";
	}
```
It dynamically populates the field perfectly. But when I try to dynamically populate with a variable:
```
$name = $this->get_field('name');
echo $name;
	add_filter("gform_field_value_jobname", "jobname");
	function jobname($value){
	return $name;
	}
```
It doesn't work. I know $value is set, I just can't seem to figure out how to get $value dynamically populated!

Any thoughts?

Shouldn't $name be inside your function?

Ideally yes, but $name in this case is drawing from an outside database:
```
$name = $this->get_field('name');
```
And I can't use the database object from within the function :)

Hi Steve,

Assuming that your "echo $name;" is working and the $name variable is correctly being retrieved from the outside database, declaring the $name as a global inside the jobname() function should allow you to access that variable. Currently, the $name variable is not within the scope of the jobname() function.
```
[php]
function jobname($value){
    global $name;
    return $name;
}
```
