Hello, I need any help to try to solver this problem... I want to calculate a sweetener intake = food consumption x sweeteners concentration in food I have a first data base (table A) with the food consumption of 2000 participants (IDFolder). Each column refer to a food product/brand. And in each column, the values are the food consumption. FOOD CONSUMPTION BRANDS Idfolder (participants) Sprite1 Sprite2 Sprite99 Sprit100 Schweppe Schwepp2 Schwepp3 Schwepp4 Schwepp5 ISP1002 2 4 5 4 7 8 6 6 2 ISP1018 4 6 2 3 8 4 7 86 4 ISP1027 5 8 1 1 5 5 2 2 5 ISP1033 8 7 5 5 3 8 2 1 7 ISP1034 1 5 4 4 4 4 3 3 65 ISP1065 9 4 8 8 5 0 1 1 5 ISP1068 7 8 4 5 441 5 0 0 4 In a second data table (table B), I have the concentration in sweeteners (aspartame, acésulfame-K...) for the food products. Concentration (mg/ 100 ml) Aspartame Acesulfame-K Cyclamate Saccharine Sucralose Sprite1 0 0 0 0 0 Sprite2 0 0 0 0 0 Sprite99 9,3 14,3 0,2 0 0 Sprit100 1,9 3,4 0,2 0 0 Schweppe 7,2 8,8 0 0 6,9 Schwepp2 0 13,4 0 0 10,0 Schwepp3 14,1 18,9 0 0 0 Schwepp4 3,8 4,8 0,2 3,8 0 Schwepp5 0 14,8 0,2 0 7,2 I would like to multiply for each food, the food consumption column (1 full column in table A) by the sweeteners concentration in this food (a single case in table B). I don't know how to do and if it is possible... or maybe, i should arrange or modify the dataset B. if someone could help me, i would be very grateful ! Thanks and have a nice day,
