eBook help video?...

Are there any demonstration help videos on creating an eBook? Currently I am struggling with the pages Having a laid out example would really help.  

I would like to do an eBook version of my help pages to send to some people. Hopefully I can use the current help worksheets. The are formatted based on the Maple help structure.

My currrent structure in the help section is:

Rational Trigonometry

      (about 40 help topics)

       RTProjective

       (about 20 help topics)

       UHG

       (about 20 help topics)

     Edit:- I have made a small step of progress using the " Assistant eBook template" but I am getting this error on build. I don't know how to find the cause of the error.

Merging lists, with overriding...

I am trying to select from a default list and a modified list to get a third combined list of the unmodified default elements and the mdfified elements plus extra elements. This is for plot data. I have managed to extract the colour data using something I did a couple of years ago. Though at this stage I don't relly know how that works either but it works.

Insetr Table seems to default too test inpul in the cells. I am inserting it from this icon 

I can't figure out how to change the whole table to 1d or 2d math input without individually changing each cell..

What am I misssing here?

Conflict of overloaded procedure paramet...

procedure programming overload

I have a example overloaded procdeure below. Due to '=' the optional input in the 2nd proc gets trapped in the 1st proc. I have tried various ways to get around this. Obviously I could make the  optional input in the 2nd proc non-optional if all else fails. Is there a way around this?

option overload;
if not(has([_params[2]],point)) then #if true need to go the next proc

print("1st proc ",l1," ",l2);
return
end if;
end proc,

proc(l1::{`+`,`*`,`=`, `symbol`,procedure,not(list)},
