Make sure that you have the L2 vlans assigned to the access ports or turnks are connected and up in order to get the vlan interfaces in up state

Hi
1) make sure you have created vlans in vlan database
2) I would change/force uplinks to trunks mode (switchport mode trunk) instead of "mode desirable" and as marwanshawi said, make sure they are UP
