I am using the app for customers to order apparel from me. Currently, I have set up loop screens for each item with the particulars contained within (i.e. size, style). There is 1 summary screen at this point for one of those screens. What I need to know is this. Is there a way for me to basically set up ITEM INFORMATION, CUSTOMIZE, SUMMARY for each item and then have a separate field total all of the summary screens for a grand total?
