Replace spaces in a string

I am building an expression in K2 cloud. I need to remove spaces from a string.

DISH NETWORK LLC

should be

DISHNETWORKLLC

I am trying to use Replace, but nothing I’ve tried works. 

I tried using \s, as well as single quotes and double quotes. Nothing takes out the space.

Thanks in advance!

Note, this is in building a view/form, not in workflow.
