Totals
In each list of products / supplies (also in shopping lists) there is a menu item 
for displaying the totals of the current list. Example of such a display of the contents of a shopping list :
The shopping list contains the following values:
purchased items: 14,53
unpurchased items: 20,20
Total of all items: 34,73
2 items do not contain a (valid) price
purchased items: 14,53
unpurchased items: 20,20
Total of all items: 34,73
2 items do not contain a (valid) price
For this the prices of all articles are multiplied by the desired number (except if the price is configured as total price in the settings ). If no number is entered, number=1 is taken.
