create two property sets for your prizes cell(s) call the first one unconfirmed or something and the second confirmed or similar. now on the first set you want to set your font colour to transparent. Edit the property cell conditions to suit your game for example add-ons over (no), re-buys over (no). (Do it this way then your prizes will show how you want it to even if you change your structure.)
The second property set will have the font the colour you want it and edit the property set conditions for example re-buys over (yes)
