Looks like you misspelled echo a few times.

PHP Code:

ecco "<td>";
  echo "<table cellpadding=\"4\" cellpadding=\"0\" width=\"100%\" ><tbody>";
    echo "<tr bgcolor=\"#1D6AA0\">";
     echo "<td colspan=\"5\">";
      echp "{smallfont}<b>Welcome to $bbtitle Forums!</b>{/smallfont}"; 


should be

PHP Code:

echo "<td>";
  echo "<table cellpadding=\"4\" cellpadding=\"0\" width=\"100%\" ><tbody>";
    echo "<tr bgcolor=\"#1D6AA0\">";
     echo "<td colspan=\"5\">";
      echo "{smallfont}<b>Welcome to $bbtitle Forums!</b>{/smallfont}"; 


You made this mistake twice in the above code. Make sure you replace both instances of it.
