PPH Installation problems

I installed the pluging but I ran up against some PHP errors.

I am currently stuck on wp-content\themes\hueman\functions\class-tgm-plugin-activation.php on line 2001

with this message: Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ‘,’ or ‘;’

Below is the way the page installed:

/** Output error strings if an error has occurred */
                if ( $this->error || ! $this->result ) {
                    if ( $this->error )
                        echo '<div class="error"><p>' . sprintf( $this->upgrader->strings['skin_update_failed_error'], $this->plugin_names[$this->i], $this->error ) . '</p></div>';
                    else
                        echo '<div class="error"><p>' . sprintf( $this->upgrader->strings['skin_update_failed'], $this->plugin_names[$this->i] ) . '</p></div>';

                    echo '<script type="text/javascript">jQuery(\'#progress-' . esc_js( $this->upgrader->update_current ) . '\').show();</script>';
                }

This is where I am currently at- but the message hasen't changed one iota!

if ( $this->error || ! $this->result ) {
                if ( $this->error )
  <strong>line 2001                 echo '<div class="error"><p>' . sprintf( $this->upgrader->strings['skin_update_failed_error'], $this->plugin_names[$this->i], $this->error;) . </p></div>;</strong>
                else
                    echo '<div class="error"><p>' . sprintf( $this->upgrader->strings['skin_update_failed'], $this->plugin_names[$this->i] ) . '</p></div>';

                echo '<script type="text/javascript">jQuery(\'#progress-' . esc_js( $this->upgrader->update_current ) . '\').show();</script>';
            }

NOTE THAT I CHANGED “</p></div>’ ;” TO ” </p></div>; AT THE END TO “OF THE LINE BECAUSE THAT IS WHAT WAS REQUIRED TO FIX THE PREVIOUS ERROR.

I know you said you are not into PHP but Just though I would ask if you happen to have a clue on this one. It’s been stumping me for awhile !
This is the way it originally looked: I also added the “;” before the ending “)”
