Replace Table Cell Values in RT Field

I am trying to update cells in a table (contents of a RT field) using the RT Range method “FindandReplace” with cell values from another table but without any success. I know the underlying problem is that the cells I am trying to update have no values in them because I create an empty table (using AppendTable using rows and columns only). Can anyone help? Have searched the forum but not with any success…obviously. Thanks for any asisstance.
