Hi @Bubba1 ,
1、expend forms by radio,checkbox
About expend the form based on the choices about Radio, you could set the form’s Visible: If(Radio2.Selected.Value="Yes",true,false)
About expend the form based on the choices about Checkbox, you could set the form’s Visible: If(Checkbox1.Value=true,true,false)
2、submit serval forms at the same time to the same record:
I recommend you use the function of Patch instead of SubmitForm.
Form1: to fill in the column of Title
Form2: to fill in the column of price
Foem3: to fill in the column of amount
Set the button’s OnSelect:
Patch(fruit,Defaults(fruit),
{TitleataCardValue23.Text,
price:Value(DataCardValue13.Text),
amount:Value(DataCardValue3.Text)}
)

3、I recommand you use servel forms in one page.Choose the fields you need in every forms.
