Data master won't update
I'm using the JIM 9.7.1 and have been trying to replicate my screen like the one shown on this link: https://www.youtube.com/watch?v=e-3t0-84kiU&ab_channel=Justinmind. The data master just won't update.
I also downloaded a file from this link as well: https://www.justinmind.com/community/attachments/873?token=e734c8cf8fbf79215f1007c9247579f4.zip and it doesn't work either as you can see in the screenshot below that the data in the data master is not updated.
I've attached my file in case you can help. In the prototype, when you tick on a checkmark and click the save button, the field called flag at the far right of the data list is updated to 1; however, this number is not recorded in the master data table.
I spent several hours working on it and still couldn't find the problem.
