Having loaded the latest version of RELMA (V4.2 build 3644) over the past few days, whenever I attempt to map a code against a local test term, the following error appears. ‘Sorry but an error has occurred, do you wish to continue? Conversion from string “12/30/2009” to type ‘Date’ is not valid.’ Clicking the ‘Yes’ box allows the user to continue. Clicking ‘No’ drops the user right out of the RELMA mapper. I imagine this error relates to the fact that in Australia we use the British style DD/MM/YYYY date format, but this has never been an issue under previous versions of RELMA.
