Receiving an "undefined" output when using correct name

[GISCQG]

I am receiving "undefined" in my custom output file even though these sections were filled in on the survey.

In the survey the CO2, CH4, O2 and H2S inputs were filled in. Interestingly enough they seem to work in the default template on the site, however if I download the default template and use it as a custom template it returns "undefined".

Hi - Can you share your survey form and report template? I will try to replicate this behaviour.

Thanks

I have just remade the survey and template from scratch and everything is working as intended.
