I had similar problems with I set up a tree over an SQL method. I don't recall exactly how I fixed it, but I can show you what I have: DTML Method: <dtml-let CatID="0"> <dtml-tree id=CatID branches_expr="CatCats(CatParent=CatID, Approved=1)"> <dtml-if "_.int(CurrCat) - _.int(CatID)"> <dtml-var PrintCat> <dtml-else> <b><<<dtml-var PrintCat>>></b> </dtml-if> </dtml-tree> </dtml-let> SQL: SELECT * FROM Categories <dtml-sqlgroup where> <dtml-sqltest CatParent type=int> <dtml-and> <dtml-if "_.int(Approved) == 1"> <dtml-sqltest Approved type=int> </dtml-if> <dtml-if "_.int(Approved) == -1"> Approved=0 </dtml-if> </dtml-sqlgroup> ORDER BY CatName PrintCat is a DTML method that displays the data on the current node. CatParent is the table field that points to parents of nodes. CatID is the field that holds the ID of the current node (which may be pointed to by some CatParents). You can ignore all the logic around "Approved" (I have nodes that aren't always visible). The business with CurrCat is an attempt to highligh the currently selected node in the tree. -- J C Lawrence Home: claw@kanga.nu ----------(*) Other: coder@kanga.nu --=| A man is as sane as he is dangerous to his environment |=--
