If you do it in several other locationsand it hasn't been biting you, you may have beenlucky (or unlucky, depending on one's viewpoint:-).I would suggest a different approach -- do a simpleloop without deletion nor recursion, just keepingtrack of 'state' ("how deeply nested am I") soyou can decorate the output with the appropriate<UL>, </UL> and <LI> tags as depth increases/decreases/stays above 0.Alex
