Thanks for your reply! I actually tried using both the Doubleclick script and the Adwords script from the thread you referenced.
Anyway, I double checked, and the paper we’re delivering to are using DFP… I’m a bit new to all this, so I think the issue is that I’ve used the wrong validator; that is, using the one for Adwords when I should have checked with the DCM one
Anyway, to get around what I thought was a limitation, I put the legal text in a tab that expands and closes again with mouse over and mouse out… Using the DCM validator however, the legal button tap event (on mouse click) is okay.
So this was pretty much a non issue, just me being a bit confused
