InfoPath Dev

Hi all, I need your advice please, I am working on a purchasing system so there is a line with an item price, the user can add more items and at the end I need to generate a price total for all items. This article https://support.office.com/en-us/article/sum-a-column-of-numbers-in-a-repeating-table-0dc91f1a-89bb-4cb1-8e32-b4ff644c4e7d#bm2 describes exactly what I need to do in terms of functionality. But the steps are not working for me especially the footer aspect, maybe because they are using an older version of infopath, I am using 2013. Hope you can direct me what I need to do. Many thanks Eihab

So- the footer doesn't display? You don't have the option to display a footer? Can you give some additional info on what isn't working? You can attach a screenshot or your template under the options tab in a reply if that helps to clarify :-)
