i didnt test this, but you could check if the file exists before you try to play it
elseif (!view == $strip($1)) && ($strip($2)) {
if ($exists($2)) { play $chan $2 }
else { .msg $chan I do not have that file $+($nick,$chr(46)) }
}
also
menu "Check One of The Following", 11
would be better as
text "Check One of The Following", 11, 2 2 71 8
