Hi

Could someone help me with the formula to multiplicate the values entered by the user in the repeating table and the find the running total of the same.

Say for example: I have 2 textboxes in a repeating table, called volume & price

in the first row i enter some value to textbox1 (volume) and textbox2(price) similarly 2nd & 3rd.

SNO.    Volume      Price
1.          250           $6
2.          180           $40
3.          100           $10

Final Total Should be : 9700 (250*6 + 180*40 + 100*10 =9700)

Oh, you are going to need the eval function for this! Here is a link with more info: http://www.bizsupportonline.net/infopath2010/infopath-math-functions-repeating-fields-input.htm
