Often we have to revise estimates for a customer, and they may come back and order against an estimate that is not the most recent. I am trying to find the best way to tie all the estimates together with the same Estimate or Job #, and increment a revision #. So far I've created a Job# field, and a Revision number field, but having trouble getting the revision number and job number to increment correctly when I have a new estimate vs a revision. Any suggestions?
