Pandora Directive query

I am finishing day 3, assembled photo and trying to buy the photo analyzer at the electronics shop. I have looked at it, asked the shopkeeper about it, but no prompt comes up allowing me to buy it. I have enough money to buy it, I'm probably missing the obvious but can someone help!?!

Page, when you got the photo from the jacket on the roof, did you also get a cuff link? If so, then when you get to your office, examine the cuff link first, then the photo. When you assemble the photo, you should hear Tex say something about analyzing it. This is the trigger for buying the machine.
