Welcome to the community, @kisuuletim12! Would you mind validating your xlsform through this online validator? It should help you identify the syntax errors present in your xlsform.
As a quick check copy C24_Does_anyone_in_your_Household_own_Income Generating Activity and find it in both the survey sheet as well as the choices sheet of your xlsform. Looking at your variable name I see that you have a space in between the variable name which is not allowed. Maybe you could fix the same as C24_Does_anyone_in_your_Household_own_Income_Generating_Activity where I have removed the space in the variable name.
