[Gretl-users] Define new variable in the GUI

Hello, I am running Gretl 1.9.11 on Win 7 64 bit Question about the GUI: When I execute Save/Define New Variable (in a model tab after executing OLS) and input in the text box: scalar b1=$coeff(IAU) Everything works fine, but when after running OLS I execute Add/ Define New Variable (in the main window) and input in the text box: scalar b1=$coeff(IAU) I get the following error message: Invalid argument for function 'IAU': invalid argument for $coeff() Is this expected behavior? Thanks, Logan
