Block attribute editing

Hi, all!

I am using Solidworks 2008 SP4.0

I have made some standard blocks in my drawing file for sayreference drawing numbers, etc. I have assigned few customproperties in the same drawing file. Now I have linked, the notesin blocks created, with these custom properties. Whenever I chengethe custom properties some of those values get very correctlyupdated in the respective block attributes but some fail to update.Iam not able to find out why there is such a difference in updationsince i have done same operations on all the attributes. Can someon e come up with the answer that what would be the failingcriteria for the attribute updations?SolidworksDrawings And Detailing
