Hi,
I am new to widget creation so can someone please help me understand how to create a widget which open up on clicking 'Add' and we enter the values (example : we enter the values for two fields cost per unit and number of unit and then get a total sum) and after clicking submit the entered value is stored in another widget which is in tabular form.
After entering multiple such values, I want the total of all the 'total sum' fields value in it. Please see the attached screenshot for better understanding
