Hi please take a look at the question group I created.

It has 4 questions

1. How much do you pay for your internet now? [ListRadio with 4 options "100-150, 151-200, 201-250, 251-300"]
2. What is the exact amount you pay for your internet? [Numeric, The number you input here should be based on Question 1 within the same range]
3. Has the amount increased/decreased compared to last time [ListRadio with 2 options "Increase" & "Decrease"]
4. How much did you pay for your internet earlier [Numeric, the answer should satisfy the condition based on Q2 and Q3]

But somehow it doesn't work when you choose option 2, 3 or 4 in Question 1 with a message "not answered in a valid manner". Can you please tell me how to correct this? I would prefer if no more question is to be added.

Hi,

comparison is "Q1==1", NOT "Q1=1".

I will check more intensively later.

I tried that too, but it gives me same popup error

Hi, jackuars,
well, that's because there was something wrong in your equation.

I tried a different approach:
You have the four categories in Q2: 1,2,3,4 and the ranges : "101-150", "151-200", ...
So you can calculate the ranges by (Q2+1)*50+1 - (Q2+2)*50.

Therefore I changed your validation equation to :
((Q2.NAOK+1)*50<Q2a.NAOK) AND (Q2a.NAOK<=(Q2.NAOK+2)*50)

Your second equation in Q2c is fine.

Hi,
just to add something.

When we ask for age or other real numbers and need the classification too, we ask only the number and calculate the category by a hidden equation.
Is there a special reason that you do it the other way?

Best regards

Thank you for your alternate expression, I will try it out.

The survey is conducted in this way because we needed to know that the respondents are not giving rigged answers, so that if it does validate as per their previous question, then most certainly we can know that they're not doing it in a hurry.

But most of all, what I wanted to know is that what's wrong with my question validation equation for Q2a.

If you just consider the first 2 questions (Q2 & Q2a), the first question asks 4 options, and the second question simply has a validation for a numerical input to see if it falls inside the range of the previous question.

Hi, I found what was wrong with the equation.

Else-if statements requires a else statement at the end, and should never end with elseif.

Previously the equation read as:
if(Q2=="1",Q2a>=101 and Q2a<=150,
if(Q2=="2",Q2a>=151 and Q2a<=200,
if(Q2=="3",Q2a>=201 and Q2a<=250,
if(Q2=="4",Q2a>=251 and Q2a<=300))))

I changed it to:
if(Q2=="1",Q2a>=101 and Q2a<=150,
if(Q2=="2",Q2a>=151 and Q2a<=200,
if(Q2=="3",Q2a>=201 and Q2a<=250,
Q2a>=251 and Q2a<=300)))

The only change is coming in the last part of the equation.
