Have a user picked image displayed in a table +

Hi, im trying to make it so a user can input a price and a picture from the camera, have them displayed together in a table and have the prices of all the items totalled at the bottom of the page. How can i do this? Ive gotten as far as being able to input strings to the table (from the task manager tutorial), however i just cannot work out how to do the arithmatic functions and how to group a image and a price together as one unit which can be displayed/deleted together etc. sorry if this doesnt make much sense - im happy to elaborate if you want
