Re: webflow transitions (just added subject to last email, sorry!)

> Hi, thanks for the response.  I saw that syntax, but I need to do codes other than "success" "back" or "error", and I can't seem to get it to work.  Can we just create custom events on the fly?  Or are "success" "back" and "error' the only triggers we can use?  Or is there a problem with my sntax?
