Windows 7: Need help to extend logical drive spac using unallocated space in win7

I am a novice and am a bit confused.
I had two Drives (Windows 7)C: with 252 GB and D:30GB plus 14.75GB for OEM Partition.(?)
now i had shrink C: and got 101GB as unallocated space.
I tried to create new simple volume from unallocated space but it gave me message
"I have exceeded the number of partitions allowed."

Please note i dont want to format D: in any case.
Now i want to add this 101GB to D: (30GB). How can I do It?

Please help if any of you can.

please post a full screenshot of "disk management"

Sure you have 3 partitions? I think 4 because 4 is the max and causes the "exceeded the number of partitions allowed." message.

In partition wizard select DATA partition. Then convert->logical. Then resize that partition.

All logical partitions are located in one "extended partition". Use logical partitions form non-bootable partitions.
