Yes, I think there is a syntax issue. Below is what the online validator says. However, I am able to preview the form in my laptop.
I want to ask: Do you have a tubewell?
In choices, I put tubewell in two rows, 1 and 0 as names and Yes and No as labels.
Could this be why I can not ‘get selected’ form on my android?
@TushaarKOBO, check the choices sheet. There should be a label missing.
I can preview my form all right but am unable to deploy my form. I get server error (500).
What should I do?
Appreciate your help.
Today morning I tried again and my form got deployed and I could also download it on my android.
Sorry to have bothered unnecessarily, and thanks a lot.
@TushaarKOBO great to hear that you have finally solved your issue. 
I want that if (tubewell) tw is equal to either dtw, etw or stw or either two of them or all of them, the respondent is a water seller; else a water buyer. I tried the following but did not work. can you pl help? Earlier, I tried ‘or’ instead of ‘and’ but that excluded respondent having 2 of three or all three and called them water buyers. Also in that case, ‘water_buyer’ came up on its own and changed only when respondent had a dtw or etw or stw.
if((${tw}=“dtw”)and(${tw}=“etw”)and(${tw}=“stw”), “water_seller”,“water_buyer”,"")
Any guidance appreciated.
Thanks.
I also tried this; but with similar results:
if((${tw}=“dtw”)or(${tw}=“etw”)or(${tw}=“stw”)or((${tw}="dtw"and ${tw})=“etw”)or((${tw}="etw"and${tw})=“stw”)or((${tw}="dtw"and${tw})=“stw”)or((${tw}="dtw"and${tw}="etw"and${tw})=“stw”), “water_seller”,“water_buyer”)
Hello @TushaarKOBO,
this seems a problem of your if logic, not of KoBo, please. You may develop and test your if clause step-by-step, starting with a small combknation.
Can you please tell me what is wrong with this calculate formula?
if((${yd}<1000),150, if((${yd}>1000), and (${yd}<2500)), 200, if((${yd}>2500), 250,’ '))
I want to say that labour needed is 150 days if crop yield is <1000 kg/acre, 200 days if yield is between 1000 and 2500 and 250 days if yield exceeds 2500 kg.
Regards,

Hello @TushaarKOBO,
remove the comma before the and.
You may always check your form during development with the Online validator ODK - XLSForm Online v2.x
Thanks so much. It did the trick.

This didn’t work for me…if I put 1 , the result is 1. How can I figure out that.
Thank you.
Hi @estalyly, welcome to the community,
Can you share a screenshot of the calculation you use so we can take a closer look?
It seems you are using the q1 in your note, so it shows the answer of the q1, you need to use the question label of the calculate question
