using a define value

I have declared some values as define statements, like: define("_ERROR1","Error: Your value is wrong, please check params"); But while trying to be called based on parameter, is not possible to call them via: $myerror = "ERROR1"; echo "<strong>ERROR"._$myerror."</strong>"; It not works. Any suggested solution without using "_ERROR1" like a variable ? -- saludos, J.
