help! I can't insert TC value. the window that pop-up too small and can't enlarg

I ask friend and she said she had same problem with me. I need to complete my take home this tuesday. So any advise please help

Could you please post your STAN model or a picture showing the process with all of its inputs and outputs?

I think, I know what the problem might be: as long as you haven't connected at least one output flow to your process, the transfer coefficient matrix is not visible (displayed collapsed).

hey! thank you . I add output flow and it really work. Thank you so much!
