Good morning!
You do two calls to Patch, so naturally you get two records in the database. If you want only one record, you have to make only one call to Patch!
Patch(Table1_1, Defaults(Table1_1), {NAME:User().FullName,RESULT1:Checkbox1.Text, RESULT2.Checkbox2.Text})What you also might want to do is to check if a checkbox have been clicked, so you have to add an If-statement:
Patch(Table1_1, Defaults(Table1_1), {NAME:User().FullName, If(Checkbox1.Value, RESULT1:Checkbox1.Text), If(Checkbox2.Value, RESULT2.Checkbox2.Text)})
Lastly, you might want to store the current user in a variable at app start, using either Set or UpdateContext, so you don't have to do the time consuming call to User() every time.
Good luck!
