Google Calendar not syncing
 

I have a Bold running on BIS. I have setup my personal E Mail account from my ISP and I can get and rec mail fine. I added Google Mobile Apps (I use G Mail a lot as well as the Google Calendar) and I can send/rec mail from G Mail fine. I can view my Google Calendar and its correct but when I look at my default Blackberry Calendar it only show 4 items (should be around 40). I try to sync and it does the sync but does not add anything to the BB Cal. I make a test entry on my PC and do a sync...it shows up in the Google Cal on the BB but not in the BB Cal. If I check the options on the Cal I see that it lists my ISP provided E Mail address. When I check in the BB options/advanced options/default services I see my ISP E Mail address for Calendar...I can not change it to point to my Google Cal. Any ideas how to get my BB Cal to check my Google Cal instead of my ISP?
