Statement expected but Function found error in my function code

问题

So below is the module of code I have created to verify a user input is between a range but this error keeps appearing below it ' statement expected but function found', any ideas anyone? Many thanks

function get_choice(var Options: integer): integer;
      var
      choice: integer;

      begin
        while (true) do
          begin
              write('choose option 1 to', Options);

              try
                readln(choice);
                if (choice>=1) and (choice <=Options) then
                    get_choice := choice
                else
                    write('invalid range');
              except
                 write('not a number');
          end;
      end;

You missed an end:

              try
                readln(choice);
                if (choice>=1) and (choice <=Options) then
                    get_choice := choice
                else
                    write('invalid range');
              except
                 write('not a number');
              end;
         end
      end;

Try try..except block must have its own end.

As Sharam already stated, you missed the end of the try..except..end block. Nevertheless, I think I can enhance the answer a bit with some tips, to help avoiding this in you future.

• keep your (begin .. end blocks on the same column. Same for try..except..end, try..finally..end and repeat..until blocks off course.
• make use of the IDE's option to connect the begin and and blocks with lines. "structural highlighting. Check the attached screenshots.
