Why can not I grab the missing character using !grepl()

I am trying the code below so that if there is neither "/" nor "\" the output is an error and the application stops, but it does not work. I cannot see any thing wrong with the code.  Does any one sees any thing wrong?

 if (grepl("/", OUTpath, fixed=TRUE)) { # mac style
     OUTpath<- paste(paste(unlist(strsplit(OUTpath, "/", fixed=TRUE)), collapse="/"), "/", sep="")
   } else
     if (grepl("\\", OUTpath, fixed=TRUE)) { # windows style
       OUTpath<- paste(paste(unlist(strsplit(OUTpath, "\\", fixed=TRUE)), collapse="\\"), "\\", sep="")
     } else
       if(!grepl("/", OUTpath, fixed=TRUE) || !grepl("\\", OUTpath, fixed=TRUE)){
       trueFalse = FALSE
       errorMessage("Unrecognized path separator in OUTpath or no path specification in PARAMS file. Cannot open connection\n
                             You can edit your input file and save the changes. Afterwards, stop and restart glycoPipe and upload file again")
       stop("Unrecognized path separator in OUTpath\n")
     }
