Error: Bad Function T and quote a list with variables

What does this Error Message mean : Error: Bad Function T?

I tried to do a while loop

(setq repetition 0)
(if (= flag1 2)
   (while ((and (>= tpagen 2) (< repetition tpagen))
     (setq pp (strcat (itoa repetition) " OF " (itoa tpagen)))
     (setq repetition (+ 1 repetition))
     (Choose)))
   )

flag1 is a user input value.

"Choose" here is a function that is defined, it runs fine once, but at the end, autocad give me that error message.

At the end of the code, I put

(setq basepointtx (+ 135.5 ( * 1000 repetition)))
(setq basepointt (list basepointtx 88))
(command "pasteclip" basepointt))

I wonder if the error is caused by not quoting the the point. How would I quote a point that has a variable in it?

Thanks!

You have extra bracket before the function AND.

What is the value that is assigned to the variable 'tpagen' ?

What is the value that is assigned to the variable 'tpagen' ?

(action_tile "accept" "(setq tpagen (atoi (get_tile \"Size\")))")

It is a user input. It is all the positive integer.

I want the while loop to run the "tpagen" times.

I think that extra parenthesis might just solved the problem. HA. However, is there a way to quote a list with variables?
