You issue is how you are retrieving your data. Firstly assuming that this is a new form you are submitting the data does not store in the Data Cards after submitting. What you can do however, is retrieve the last submitted record by using the LastSubmit function, which retrieves the last record submitted to the Data Source.
Set('variable name', 'Form Name'.LastSubmit)
Now you would retrieve the data from the variable. To get the Name of the person selected in the People Picker use the code:
'variable name.'People Picker Column Name'.DisplayName
For the two choice fields you can retrieve the data by using the code below.
'variable name.'Choice Column Name'.Value
