Token Comma expected

Hi all. This is my first post so I'm hoping to get this right. 

I've removed a piece of code by accident and I'm getting the following error of Token Comma expected. I go to show error and it highlights the piece and I insert a comma before it but this doesn't solve it. 

Any extra piar of eyes would be really useful here. Pleasae
