else if (CharToAsh.charAt(x) == " "){
nextWord(); }

}
}

}

}

:confused: Please. Can someone tell me whats happenning?

Its wrong for the 4 else if at the bottom

You've only posted a code snippet so I can't test but my guess is you need to change for example:

KnightRag:
if (CharToAsh.charAt(x) == "!"){

to:

 if (CharToAsh.charAt(x) == '!'){

From : http://www.arduino.cc/en/Reference/String

strings are always defined inside double quotes ("Abc") and characters are always defined inside single quotes('A').

Please in the future:

  • Do a Tools > Auto Format on your sketch
  • Remove unnecessary whitespace
  • Post your(complete) code using code tags(</> button).
  • Post the complete error message using code tags.
