activated folder and relative data path

Hello,
Here is my structure :
[code][b]
MyDataBase
|— MyDiagram2D
|— First Folder
| |— subFolder1
| |—subsubFolder1
| |—subsubFolder2
|— Second Folder
| |— subFolder2
| |—subsubFolder1
| |—subsubFolder2
[/b][/code]
I want MyDiagram2D to be feed with data comming from subsubFolder1 AND subsubFolder2 of one of the subFolders depending on witch one (of the subFolders) is activated.
If i put [code]
for curve 1 : [b]./subFolder1/subsubFolder1/MyXData[/b]
for curve 2 : [b]./subFolder1/subsubFolder2/MyXData[/b][/code] in the x-data set of my curves, it doesn’t work.
Could you please expalin me how is it possible.
Thanks.
