Hi,
got a little problem with XDocument. I use XDocument to get a value from an XML document. Everything is working fine but I get an error (Object reference not set to an instance of an object) when I try to debug the project...but it's working when I click next. This is my code:
I do assign the value from a combobox and I can display cbt so the value seems to be assigned correctly
Then I start the sub with XDocument
The error (Object ...) is pointing to "Dim ssk = correspondingValues.SpezSchnittkraft" but yeah, when I click on next and ignore the error everything is working

Label3.Text = ssk
