I have already filled in all the information on all the sections,the only problem is that when I completed filling in all the referees information the status still says PART COMPLETE, instead of COMPLETE. I have entered the information for three referees. I assume that this is why I can't submit the all the information to apply for my ATAS certificate. Already tried using Google Chrome and Internet Explorer, and all other sections have the COMPLETE status.

Have you tried contacting the organisation directly?

Hi.
Actually, I have already sent an email to the support team, but if someone has experienced the same issue it would be very helpful to know if it was solved somehow.

How many references is it asking for? Just try to put some random information in another reference field and see if it will accept it then?
