I still have the error but I have made a few changes since posting which I thought I should make those of you trying to assist me aware of.
After checking it over visually I found I am not familiar enough with HTML to identify the error, so I turned to sites which would check the HTML code for me and notify me what specifically is the source of the errors. The first site of this nature I tried was https://www.freeformatter.com/html-validator.html
It found 16 issue:
1)
The character encoding was not declared. Proceeding using “windows-1252”.
Code Extract:
Issue 1 is not of concern for me.
2)
Element “head” is missing a required instance of child element “title”.

Issue 2 was solved by Including <title>Don’t panic! This is the title</title> within the <head> section.
The issues between point 3 and 15 were all the same and solved by changing Row A to the following:
<!-- Row A -->
<tr>
<td colspan="3">Part No.: </td>
<td colspan="7">Product Record</td>
<td colspan="2">Name: </td></tr>
This also solved issue 16.
Despite solving all these issues I still got the error message informing me that the expression is still not valid.
