Various index match problems

I know there are lots of versions of this problem on the web, but I'm not good enough at Excel to be able to change them to fit what I need,

On the attached workbook, on the "Progress Summary" page, cell C30 has a formula which should list the names of pupils who made 0 progress (as referenced by the Raw Data page, column R [progress] and column A [name].)

It only lists the first name and not all of them. Can anyone help me?
