I have no experience using VBA, but I am comfortable with javascript and open to learning. Just wanted to check that there was not already an easy solution to this that I am missing, before I dedicate time to learning something big.

Is any good way to trigger an alert window (i.e. a user prompt or popup) when someone clicks a particular hyper link. So that, for example, the hyperlink could say: "The referenced document has been attached to this memo as appendix 1, to continue to the original online version please please click "Continue" otherwise x out of this box." And then have the user be redirect (as a normal hyperlink would be) to the page, if they click continue.
