DMS Form Help

So I was trying to fill in the form for MBA at IITD but I keep getting an error while inputting academic details, particularly 10th marks. I gave the CBSE boards and so am entering a percentage but it keeps saying "Fill aggregate marks details properly." and keeps taking me to that cell. Any help would be appreciated or if y'all know whom to contact that would be great as well. Thank you https://preview.redd.it/wzgrpe0sgy7e1.png?width=1369&format=png&auto=webp&s=d9cccc1c56e9e7d83907bb671fad2fb535cebc5e
