Hi, Assignment -> Resonances pops up the Browse resonances popup. If I change ShiftList (I have two for different conditions) I get Exception in Tkinter callback Traceback (most recent call last): File "/usr/lib64/python2.2/lib-tk/Tkinter.py", line 1316, in __call__ return apply(self.func, args) File "/usr/local/ccpnmr/ccpnmr1.0/python/memops/gui/PulldownMenu.py", line 162, in <lambda> command = lambda n=n: self.setSelectedIndex(n) File "/usr/local/ccpnmr/ccpnmr1.0/python/memops/gui/PulldownMenu.py", line 294, in setSelectedIndex self.callback(selected_index, self.entries[selected_index]) File "/usr/local/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/BrowseResonancesPopup.py", line 224, in changeShiftList shiftLists = project.findAllNmrMeasurementLists(className = 'ShiftList') NameError: global name 'project' is not defined -- Dr. Brian O.
