Respondents are asked to select a number in the dropdown menu for each question.

I want to show respondents an amount of money live on the page, based on their selected answers.

So let's say I have a base amount of €20 and the value of the item shown as Question 1 is €4 per level.

So if a respondent selects the number 1, I want an automatic calculation to show: €24 (base (€20) + 1x€4). If the respondent selects the number three, I want the automatic calculation to show €32 (base (€20) + 3x€4).

I want to combine this for all four select questions on this page.

I understand that I cannot use an Answer Label, since I want this calculation to occur on the same page as where the respondents are selecting their answers. How can I achieve this?

For the "SelectQ" questions, respondents can select a value from 0 to 5 (for Q1, Q2 and Q4), and 1 to 5 for Q3.

I want to multiply the value of Q1 by €4 and the value of Q2, Q3 and Q4 by €1.

I want to add these numbers to a base amount. I want to obtain this base amount from a list which I will construct, in which the Index is based on an answer to an earlier select question.

And what is the line of code I can input in my text to show the value?
