How should the counselor attach the Grade Transcripts!

I need help
I have 3 Grade transcripts for the 3 last years, My EC scanned them, but he can't attach them to the international supplement and the school report only includes the most recent transcript; so what to do ?

<p>The school report provides the opportunity to upload up to four transcripts. Just advise your counselor to click the "Add Transcript" button on the online School Report.</p>
