Problem with numeric format on a layout
I am using FMP 12 with an academic gradebook application. I am having a problem in formatting numeric fields on one of my report layouts. Several fields on that layout list grades for exams and are best shown in a percentage format. When I attempt to change my layout fields to percentage (2 decimal) format using the layout inspector, the results (after I save my layout) show a question mark (?) symbol in all records for that field. However, if I change the numeric format to decimal format (2 decimal places), the same field displays properly (but not optimally as a percentage). Can someone offer a guess as to why this is happening and is there any workaround to display my layout numeric fields properly as a percentage? Thanks for your help!
