Help with scripting

Hi, am a student and i have homework about bourne shell script and i am having difficulties because i've never written this kind of scripts.

1. The problem statement, all variables and given/known data:
So i have to write a script that check if files header.txt, content.txt and footer.txt exist.
If they exist i have to read every one of them and use the lines without "#" and to generate HTML file with this data ( the data from header.txt shoud be copied between header tags, content.txt between body tags and footer.txt between footer.tags. Atleast i am understanding it like that) After that i have to check if the HTML file modify date is older than the other 3 files to create a new one HTML file., but if the HTML file is newer to exit the script.

2. Relevant commands, code, scripts, algorithms:

3. The attempts at a solution (include all code and scripts):

Code:

#!/bin/sh
echo "Enter folder path: "
read path
cd
cd $path
file1="header.txt" 
file2="footer.txt"
file3="content.txt"
file4="project.html" 
if [ -e $file1 ]
  then echo "Header.txt exists"
  else echo "Header.txt doesn't exists"
fi
if [ -e $file2 ]
  then echo "Footer.txt exists"
  else echo "Footer.txt doesn't exists"
fi
if [ -e $file3 ]
  then echo "Content.txt exists"
  else echo "Content.txt doesn't exists"
fi
if [ -e $file4 ]
    then if (test $file4 -ot $file1 -a $file4 -ot $file2 -a $file4 -ot $file3)
           then   # create new HTML
           else exit()
         fi
  else 
    cat > project.html<< eof
    <body>
    <header> 
    cat >> header.txt 
    </header>
    cat >> content.txt
    <footer>
    cat >> footer.txt
    </footer>
   </body>
   eof
   echo "Project.html has been created"
fi

Can you help me with the script how to create the HTML file and copy the data from the other 3 files(without the lines starting with#) in the HTML file because i am obviously not doing it as i shoud. I did the check for the file and i think i did the check for the modify date, but something about creating the file and copy the data dowsn't work. this is the peace of code for help

Code:

if [ -e $file4 ]
  then if (test $file4 -ot $file1 -a $file4 -ot $file2 -a $file4 -ot $file3)
           then   # create new HTML
           else exit()
         fi
  else 
    cat > project.html<< eof
    <body>
    <header> 
    cat >> header.txt 
    </header>
    cat >> content.txt
    <footer>
    cat >> footer.txt
    </footer>
   </body>
   eof
   echo "Project.html has been created"
fi

I check for the project.html (file4), if it exist it should compare the modify dates and if the html is older to create new one, or if it isn't older to exit. Else If the html doesn't exist just to create one.
