What she's saying is there aren't instructions for her set.
http://playmodb.org/cgi-bin/showinv.pl?setnum=4029 What you could try though, Betsy, is to browse through parts on that website. go to search by category and try to narrow it from there. You might be able to figure out what you need. It could have been available in another set that does have instructions. Then once you find the part, it will show you all the sets that part was ever in. Then you can start looking for those sets, or parts from those sets. You could also try to order the part you need from playmobil, but they are not likely to have it if it's been many years since it was in any set.
In any case, if you find the part number, and post here exactly what you're looking for, we can probably be of more help.
