Problems How i can make a list with words that includes values?

Can someone help me with these to problems:
1) How can I make a list with words that includes values? For example when I choose "A" from the list it has value of 1 in a calculation and when I choose "B" it has value of 2 etc.
2) How can I copy calculation result from one screen to another?

1) Two lists:

A,B,C,D,E

1.2.3.4.5

Get index selected from first list, then get corresponding index from the second list to use in calcualtion

2) Use a tinydb to save data that is accessible across screens, or make the calculation result the "start value" for the next screen.
