troubles embedding a spreadsheet

troubles embedding a spreadsheet

I have embedded another spreadsheet in my website, but now I have got the same problems that I had in the past. You can see in the link :
http://www.planfinan.com/home/punto-equilibrio

1. Description of the chart axes are not fixed after modifying
2. Can not change the value of a cell more than once, after it appears on the bottom right "cell is protected"

I reported these two problems on another occasion when I came up with another sheet. These were solved but I thought that was fixed for all the environment of "zoho sheet" and not only for that spreadsheet.

I think it's important for users to know how aid zoho.

Thanks a lot !!
