Whats wrong in this Lisp

This lisp for coordinate

click in the points in order then create a table with the points number and X&Y

when run the routen

its pick the points and insert the point number

But can not create the table

I hope to find a solution or a lisp same like

                                     ; while this command is active...

Can you use ACAD_TABLE objects?

In fact I have no experiance in lisp

How can I use that objects?
