Error 800a9cf1

Hi all, I try to create a treeview in Excel 2010 but I get the following message: "Could not complete the operation due to error 800a9cf1". I don't understand why excel 2010 displays this message when I have created forms with treeview which functioned normally. Thanks for your help Malik Sad

You're most likely in debug mode. Get back to normal and you should be ok.
