Cannot get a summary field to update/refresh
I have a layout which includes a summary field which is calculated based on a field selection. When the field selection is made (via drop down menu), the calculation should update. I have a script trigger to refresh the layout once the field selection is made. All the fileds in the layout except this summary field update (including other summary fileds and calculated fileds in the layout). What could cause a summary filed not to update on a window refresh?
