Hi Karen,
Apologies for not replying sooner. I went ahead and added a few things to your form. Please check the section below for the repeating table. in order for you to add a fixed/permanent row to the repeating table, proceed to the data tab and locate the Default Value button. A windows will appear showing all the fields on your form. Locate the repeating group and add as much repeating fields as desired.
Once you already have a sufficient amount of rows, expand the QuestionList, click on the Question field and enter the question at the Default Value section. I have already created a sum section at the bottom section of your form and have configured the formula for you. Please let me know if this solution works for you.
Regards,
