Thanks but where do I look for that? I’m new to Acumatica, can u pls teach me where I can see that collection editor? Thanks again Mr. @BenjaminCrisman 

found it Sir, but why is this showing me duplicated details, where could I have doubled it? thanks!

found it too, now the line number started counting from the column header, here’s the picture of the designer, where am i wrong Sir @BenjaminCrisman ? Thanks a lot!

I saw it, never mind these concerns now, thank you still!
