I was not aware there was one. I did not have any documentation on flow when I installed it here at the office late last year and was not there for the initial install and did not see a manual with the one that had an extension added. I appreciate you working with me on this, and I now think I have a handle on this process. 1 Comment actions Permalink Please sign in to leave a comment.
