Everything works fine with fewer \items. Does that mean it does not support when there are too many rows? or continues to a second page?

I got the warning:

)
! Undefined control sequence.
\GenericError  ...                                
                                                    #4  \errhelp \@err@

Sorted!

I was using letters and there are only 26 letters.

So solution is to use counter-format={tsk[1])}.

On my god, the warning message is misleading!

  • If you look at the complete log you find ! LaTeX Error: Counter too large.. And if you look at the PDF produced by the example in your question it is also quite obvious :) You can also load package alphalph and tell tasks to use it: \NewPatternFormat{aa}{\alphalph} and then counter-format={tsk[aa])} – cgnieder Dec 7 '15 at 20:47
  • By the way: ! Undefined control sequence. is not a warning message but an error message (LaTeX distinguishes between those) – cgnieder Dec 7 '15 at 20:48
  • @clemens I did not ask latex to compile it once I saw the message. In general, I tend to "solve" the problem before I force it to compile. I would say there was nothing that was Undefined. All was defined perfectly. That to me was just confusing. Thanks about the other suggestion. – Chen Stats Yu Dec 7 '15 at 20:58
