Forums Scripts & Popups question on $replace and $remove

i have another question on this now..

for some reason the format changed... and now i'm getting a error:
Break: evaluation error (line 28, script4.mrc)

which is this:
%somevar = $+($chr(3),04,$replace($remove($wildtok(%temp,{*},2,58),{,},$chr(32)),|,/))


the format switch to : {hello | mom}

//echo -a $+($chr(3),04,$replace({hello | mom},|,/,{,[,},]))

but, i get a replace error... so i do this.. {hello $chr(124) mom}

and i get this result... {hello | mom} | / [ ]

how can i fix this so it so my result becomes hello/mom again... i'm kinda stumped..
