Thanks. I'll give that a try. The (Cancelled) for the memo was something I saw in another post. I'll change it to [Summary] and see what happens.You don't need two trigger URLs. Remove the first one. The flagalert and memo tags can be comined into one. Also I think your "(cancelled)" in the Cancel URL might be wrong. I just have "&memo=[summary]"
In the log file I saw this when the cancel url was called.

But I never seen the word cancelled in blueiris, nor do I have any cancelled alerts. So maybe you are correct about the cancel url.
