Enemy Combat C# Code help needed

Im only getting a single error and the code is all in, the error is, The type or namespace name 'PlayerHealth' could not be found are you missing a using directive or an assembly reference?

Here is a picture of the code http://i.imgur.com/yUDkuNb.png

 

change

Code (csharp):

1.  
2. = (PlayerHealth)target.GetComponent("PlayerHealth");
3.  

to

Code (csharp):

1.  
2. = target.GetComponent("PlayerHealth");
3.  

See if that helps

 

I changed and saved the code to yours and I am still getting the same error.

 

it should be:

Code (csharp):

1.  
2. target.GetComponent<PlayerHealth>();
3.  

 

Tried, still.
