Please help me guys!! why DBM 12 not saves?
Okay, you need to try a small experiment, to make sure you're doing it right and to make sure DBM is saving your edits:
Open up DBM 12. Create a new folder on your desktop. Use the Export All Tables function, and export all tables into the new folder. The export function is on the top left; it's an icon with two files and green arrow.
Once the tables are exported, open up the new folder. Open the third table called BigAttendance with Notepad or Excel. Change just one of the table values, making sure you remember which value you changed and what the original value was. Save.
Use the Import All Tables function and import all tables back into the db. The import function is the icon with two files and a red arrow. After the all tables have been imported, remember to save your work.
Close DBM 12. Start it up again, and once all the tables have loaded in DBM 12, look thru the list of tables on the left side, find the BigAttendance table, open it, and check to see if your editing worked.
