Hi,
Please may i know how to link variables in application buildup?

After adding questions in “multiple choice” , i need to link variables to each choice.

How do i get this done?

Thank you in advance

Hi,

Can you define “link” ?
Do you mean reference variable ? like use the question date of birth to calculate the age ?

If so, please look at this page of the wiki :
