Completing form prompts from array - error!

I'm borrowing Julie Meloni's technique of defining a form and assigning it to a variable, but want to enhance it by providing the form prompts from an array. This will allow me to accomodate different languages. Here's a code fragment ... $user_form = " <form method=\"post\" action=\"$PHP_SELF\"> <P> $arr_lbl[ lbl_cUsername ] <input type=\"text\" name=\"$cUsername\" size=10></p> <P>Email ... and so on to the end of the form ... </form>"; The problem lies with --> $arr_lbl[ lbl_cUsername ] <-- which is returning this error: Parse error: parse error, expecting T_STRING' or T_VARIABLE' or `T_NUM_STRING' in /usr/local/apache/htdocs/auction/user_register.php on line 122. I've also tried it with $arr_lbl[ \"lbl_cUsername\" ] $arr_lbl[ 'lbl_cUsername' ] . . . \"$arr_lbl[ lbl_cUsername ]\" All this is very puzzling, because just ahaed of the form the statement echo $arr_lbl[ lbl_cUsername ] works fine and prints out "Username". Any suggestions? TIA - Miles Thompson
