Thank You for your work and time.
i used the fetch metadata option you integrated in the UI, it works great.
I was unable to use other Metadata actions and properties due to my limited syntax and parameters knowledge,  can you please provide a little more data about the syntax or how to use the other actions like 2.1 and 2.3, etc ... and the in and out piid.

thank you again for providing this valuable service to us
