Try setting FileScope to Shared or Legacy
and you need to include the filename in your path!

The file name should be entered by the user...so how can i include it?

9

Use a textbox ?

You already get the file name in response, right?

11

Définissez le premier file scope sur app et le deuxième sur legacy. Et n'oubliez pas de mettre le nom du fichier...
