I tried the duplicate again and followed through to the point where I was trying to fill in the form. It seems to work for me, and all the inserted pages (within fields in them) show up in Print Preview. Can't think why it didn't work for you, 8i010g1x, but perhaps someone from Adobe will look at it .I also tried Shrutiaman's suggestion and that also worked for me (ie do Add PAge to get a new subform then move the subform down to where you want it.

Back again, having completely forgotten that I posted on this issue, but once again needing to insert a page in Design View. Still can't get it to work, although I haven't tried MayseG's solution - a last resort for me, I think. So meanwhile ... to repeat ... ISN'T ANYONE AT ADOBE GOING TO COMMENT ON THIS ISSUE?

oops: it's not a right-click, you have to choose Edit > Duplicate when you've selected the page in the hierarchy.

This seems to work: go to the page below where you want to insert the new page. Show the Hierarchy (Windows >Hierarchy). In the hierarchy, right-click the page you are on and select Duplicate Page. It will rename the page and insert a dupe, eg Page 6[0] and Page 6[1]. You can then change the content on one of the pages. That's as far as I got so far, I'll have to see if this works or if the forms filling gets completely screwed up.Mama mia!

This is unbelievable! Isn't someone from Adobe going to comment on this problem?
