I am unable to get expressions to appear in the Expression window of Expression builder when trying to change variables in a sub-report. They are in the upper window but nothing appears when I click on a variable to edit it. (Variables are visible in the main report though.) I also receive an unusual error 'Information - COLUMNS' when trying to change the data type of an expression. The expressions are there when I try to list them but cannot be changed. I have tried this on a couple of databases where this used to work. I am using 64 9.1.5.20410. If anyone has experienced this, or has any suggestions as to what I may have wrong here that would be much appreciated.
Thank you. Regards. John Docherty
