I have already estimated the equation with 8 crossid, and got the beta of X1 for each crossid, so I have 8 Beta.
I wonder if anyone can help me how to store those 8 Beta as a serie containing 8 Beta, since I have to use those 8 Beta to run another equation further.

Thank you in advance.

I am very new to eviews, and use only the equation box (cannot use the command area)
would be appreciate for your help so much.
