Notice (8): Undefined variable in cakePHP

When I updated the changes in sight, I get this error:

  

Notice (8): Undefined variable: manager [APP \ View \ Views \ browser2.ctp, line 133]

I have reviewed up and down and nothing .. I keep giving the same error ...

Similar to this I have it in another browser1.ctp view and it works perfectly ...

If someone gives me a north ....

Thanks

Here is the code ... line 133 in the original here is 35
