I'm trying to upload 5 PDF files which are under 30MB all together but the "Continue" button is greyed out and I have no idea what the problem is. I can't save anything, and I can't continue with the upload. Reloading the page causes everything I've already added in the description to be lost. I've tried in a number of different browsers and the problem is the same. TES: PLEASE could I have some assistance with this!
