How to calculate with user-defined variables

For projects where you want to sum variables and get the result with a user-defined variable:

  1. Go to Project-Properties -> Survey Options -> user-defined variables -> Select number of user-defined variables
  2. Create a new question multi text field (143), where the user can choose different numbers for the calculation
  3. Choose for the Input-Format only Floats allowed -> Save your changes
  4. Go to your new page -> Triggers -> Create a recording trigger
  5. Checkmark „Also execute trigger in preview mode“
  6. Go to detail configuration choose your definied-variable (c_0001) and insert in „value“ the variables to calculate with f.e. -> #v_1# + #v_2# + #v_3# (operators + – / * can be used)
  7. Create a resultpage (Type 998 recommended) write in the question text: #c_0001# (result of the calculation will be shown)

Hint: You can also write #v_1# #v_2# in the question text to show the values of the variables for the calulation

F.E. „The result of your calculation #v_1# + #v_2# + #v_3# is: #c_0001#
