Tree in Webdev

Hi Everyone,

I am creating a tree with the following code
____________________________________

sRoot is string
sLeaf is string


sRoot="My Projects"
TreeAdd(MyTree, sRoot,tvDefault,tvDefault, Null)

//---->Create Leaf
sLeaf = sRoot+TAB+"My Project 1"
TreeAdd(MyTree,sLeaf ,tvDefault,tvDefault,sLeaf )

sLeaf = sRoot+TAB+"My Project 2"
TreeAdd(MyTree,sLeaf ,tvDefault,tvDefault,sLeaf )

sLeaf = sRoot+TAB+"My Project 3"
TreeAdd(MyTree,sLeaf ,tvDefault,tvDefault,sLeaf )

-------------------------------------------------------------------
The problem that I have is that I cannot select some of the projects (My Project 1, My Project2 and My Project 3)

I am using the following code:

ResPath is string = TreeSelect(MyTree)
sMyChild is string = ExtractString(ResPath, 2, TAB, FromBeginning)


.....with this code sMyChild is empty


any body have an other idea ?

thanks in advance
