Whats that darn yellow caution sign?
While typing in the code, you might encounter a yellow caution sign appearing and disappearing. This sign tells you simply that the code you typed as of your last keypress has a syntax error. Either you have a typo in your code or your code cannot be used like you wanted it to work. Check out the parenthesises, the commas, the upper- or lowercase functions/variables. Pressing CTRL-Z (PC) will undo your last typing in the boxes. Pressing TAB will get you in the next text box. You can cut and paste text to and from the clipboard using shift-delete and shift-insert ( CTRL-C and CTRL-V work too). You might also encounter that your code is correctly typed, but your filter does not give you the results you expected. Check the values you are giving to your code, for example ctl(20) won’t help much, because there is no slider 21 (you have just got eight, isn’t that enough? :-)).
