sorry I am new to this community

Being new to the community does not mean you are incapable of framing a question properly. Ask on the community in the same way you would in real life, ie give details of what is wrong, what should be happening, and what you have done (screenshots of UI, relevant blocks, and if possible a video of the problem and a sample aia).
