Hi Maria Not quite sure what you mean by did I save them I had to click on a save button to export the files (I have tried twice) and I appear to have saved them because they are in the Parameters folder but when I open up the Parameters folder in UF they are not there - the only file that is there is the one that comes with UF. I think I might be going mad!! I wonder if I have a glitch in the actual programme because it doesn't seem to make any sense. Anyway, thanks for trying to help.
