Unexpected end tag (font) HTML

I am running an R code to which several HTML files are connected. As R Returns an error message, I have opened the source file from which the message results:

In the HTML file, there is the following error message:

"End tag (font) violates step 1, paragraph 1 of the Adoption agency algorithm. Unexpected end tag (font). Ignored.

As I am completely new to HTML, I would appreciate if someone told me from which the message results. Here is the code line:

<TH ALIGN="left" COLSPAN="2">Methods in <A HREF="../../../../../../org/apache/poi/hssf/usermodel/package-summary.html">org.apache.poi.hssf.usermodel</A> with parameters of type <A HREF="../../../../../../org/apache/poi/ss/usermodel/CellType.html" title="enum in org.apache.poi.ss.usermodel">CellType</A></FONT></TH>

Thanks in advance.

Solution

You have a </FONT> tag ... but you have not a beginner tag <FONT>

<TH ALIGN="left" COLSPAN="2">
    Methods in 
    <A HREF="../../../../../../org/apache/poi/hssf/usermodel/package-summary.html">org.apache.poi.hssf.usermodel</A> 
    with parameters of type 
    <A HREF="../../../../../../org/apache/poi/ss/usermodel/CellType.html" title="enum in org.apache.poi.ss.usermodel">CellType</A>
  </FONT>
</TH>

..so or you add the begin

<TH ALIGN="left" COLSPAN="2">
  <FONT
    Methods in 
    <A HREF="../../../../../../org/apache/poi/hssf/usermodel/package-summary.html">org.apache.poi.hssf.usermodel</A> 
    with parameters of type 
    <A HREF="../../../../../../org/apache/poi/ss/usermodel/CellType.html" title="enum in org.apache.poi.ss.usermodel">CellType</A>
  </FONT>
</TH>

or you should remove

<TH ALIGN="left" COLSPAN="2">
    Methods in 
    <A HREF="../../../../../../org/apache/poi/hssf/usermodel/package-summary.html">org.apache.poi.hssf.usermodel</A> 
    with parameters of type 
    <A HREF="../../../../../../org/apache/poi/ss/usermodel/CellType.html" title="enum in org.apache.poi.ss.usermodel">CellType</A>
</TH>
