The 'searchuser' GET actually requires a value you know, if you read the lines in the documentation:
implying you actually need to do '&searchuser=Broderick' or some such line, an empty field won't work. Also, you don't say what is stored in search.searchvalue, or what your error actually is (no window opens, a javascript error occurs on the page...etc). For all I know, you are accessing the html elements wrong in the first place. Nevertheless, give the first solution a shot.Code:Variable name: searchuser Values: Enter a username
