This might be due to an issue with your layout design. Please describe how you set up your layout.
Both the beginning balance field and the current balance field were set up with Global storage.
I would simply set up the current balance field as an unstored calculation. I would not make it a global field.
I suspect that you may just need to create a new record before trying to enter that value.
Thank you so much for your replies. After digging a bit deeper, I went to layout mode, selected the beginning balance field then opened the inspector. I noticed that nothing was checked in “field entry,” so I checked Browse Mode and that is all it took.
Thank you again.
