When making forms from scratch, it’s always a good idea to use the Add Existing Fields option when in ‘Design View’.
I tried to program it using code, but it has gotten quite complicated. I’ve learned that simplest is best. At least for now.
Here I’ve simply dragged the fields after pressing the Add Existing Fields button on the task bar on top, then from the field list I dragged the title that I want.
Now I was able to make individualized group sheets for each group. Next, I just have to learn to put the subdatasheet into the ‘Details’ area of the form so I can make roster sheets for each class.
