I have emailed the webmaster but there wasn't any response. Could any of you please correct the error explained below that I am encountering.

The webpage doesn't load correcly, meaning doesn't show the "table of contents list". I cannot proceed to read the material of the relevant chapter(s) without the table of contents list link working. Please correct the problem so I can continue to study.

If it would be relevant to mention the error received on one of the instances was:
Warning: mysql_result(): Unable to jump to row 0 on MySQL result index 5 in /home/virtual/site7/fst/var/www/html/index.php on line 131

The three links given are of the title pages of the chapters:

Chapter8 : Karnaugh Mapping

Chapter9: Combinational Logic Functions

Chapter12: Shift Registers

All of these webpages do not show the table of contents list which normally appears on the left hand side of each title webpage of a chapter.

Many thanks.

Hi Mirage,

I have a feeling these pages are some of the incomplete sections of the site. If you recall on the opening page of the site it says:

This site provides a series of online textbooks covering electricity and electronics. The information provided is great for both students and hobbyists who are looking to expand their knowledge in this field. Please keep in mind that the textbooks are not 100% complete. They are a continuous piece of work, and thus will continually be updated.

I will PM the site administrator and see if I can fully clarify the situation. I'm sure he will post the answer here for you.
