Hello:

I use a Docket # to identify photo assignments and want to include this in the Opportunity Object.  I would like the Docket # to toggle each time I generate a new Opportunity.  Can I use auto numbers to accomplish this?  I've tried to do so but I'm not getting the result I need.  Very simply the numbers would be as follows:  D08101, D08102 and so on.  No doubt the answer is in front of my face but I'm missing it.  Thanks.
