The problem in your original attempt was a space between the @substitute!(%)

Remove that space and everything works fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1030576 Title: cadabra failed on substitute index command To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cadabra/+bug/1030576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
