Hello,
Great to see you in the community! Wish you best of luck for your project. You can check out community guidelines to find answers more quickly by structuring the post better.
Is it possible for you to share a screenshot of your dynamo project so that we can detect the issues more easily? Normally you can get the location of tag elements using Element.GetLocation. Alternatively, you can use Element.Location+ node from Clockwork package. It will give more detailed information about the selected object.
Looking forward to hearing from you!
