If you are linking your Fixtures & Results section to an external website, to fill out a match report for each game you would first need to de-select the link to your external website (select to re-use the Club Website system). This will re-activate your internal Club Website Fixtures & Results section.
Once you've done this, you can create a fixture in the fixture area, complete the match report and then re-activate the link to your external website. In doing this, this will also update all the squad details. We hope this makes sense let us know if it does not!
