Thanks for the fast feedback guys, the code is now running perfectly fine!

I am using the following code:

`if      (gewaesser_name1.toLowerCase().indexOf("stream") === -1 && gewaesser_name2.toLowerCase().indexOf("stream") === -1) 
         {var a = "does NOT contain stream"}

 else    {var a= "does contain stream"}
