why does this display errs

[Alex fxmbsw7 Ratchev]

i was trying to make example of stuff with fifo, then i figured i shortcode
rm and mkfifo to one eval instead of type both times $fifo
but no luck

in the pasted i instead of big code only this, but the error changed, in
the big one is '{rm command not found'
nowork on both

why

x-( 1 ) ; eval {rm -rf,mkfifo}' "${x[@]}" ;'
      bash: syntax error near unexpected token `1'
