How to upgrade?

[jannie]

I oversee 3 Projects myself (female) & male cousin & brother - dna info.
I logged in under my male cousins log-in kit number, when I go to upgrade it says... you can't upgrade the test it's only for males. He has the done the Y-37, anyone offer some help? Thanks

Got it.

Going directly from the mystery coupon clicking on use it allowed me to upgrade to the 67.
