There is a search box in the upper right corner of the page that would be helpful, but here's a link to start:<br /><br /<a target="_blank" href=http://www.infopathdev.com/forums/topic.asp?TOPIC_ID=2169>http://www.infopathdev.com/forums/topic.asp?TOPIC_ID=2169</a>https://www.infopathdev.com:443/forums/thread/1265.aspxTue, 25 Apr 2006 14:33:57 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:1265Taffman0https://www.infopathdev.com:443/forums/thread/1265.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=1265I've created a repeating table to create an bill of materials.<br />I have an expression box as the last field in each row that calculates the product of "Quantity" and "List Price" to give "line item total".<br /><br />I now want another expression box in this and another view that evaluates the sub of all the "line item total" fields to produce a total order value.<br /><br />Can someone advise on the expression I should use here please?
