Is it possible to pass local storage variables between pages and display the sum of the values?

For example:

Page 1
2 options available,

• if the user selects option 'a', local system variable 'v1' is set to 1.

• if the user selects option 'b', local system variable 'v1' is set to 0.

  Page 2
  2 options available,

• if the user selects option 'a', local system variable 'v2' is set to 1.

• if the user selects option 'b', local system variable 'v2' is set to 0.

  Page 3
  I would like to display the sum of 'v1' + 'v2' in a label.
  Is this possible? If so how?
  Are there any alternatives without using a database?

  Thank you!

Hello! You can merge values and put the result into the Label using next JS code:

codevar sumValue = parseInt(localStorage.getItem('v1')) + parseInt(localStorage.getItem('v2'));
Tiggzi('labelComponentName').text(''+sumValue);/code

where labelComponentName - your component name

Fantastic, thank you!
