I get a blue Bar accross screen bottom and an error message:
Syntax error,Nesting error ar line 220,at line 220
The bar is at empty line 216 and all my code ends at line 215.Whuts'up?

a nesting error means you are missing a half to a statement such as...

DO/LOOP
IF THEN/ENDIF
REPEAT/UNTIL
WHILE/ENDWHILE

etc...

and it could be anywhere in your code...the lines db tells u are not all that accurate because it doesnt know where you wanted to place that piece of code your missing

yes
that also can be because you forgot a ENDFUNCTION command somewhere . . .
