Hello everyone, I am having an issue with Question 2 in the Hands-on 11 quiz. I ran the model using **MUIO v5.6**. In the **Use by Technology by Mode** results, the industrial LPG boiler `DEMINDLHELPG` does not appear, which indicates that its LPG consumption is zero. This also seems consistent with the Hands-on 11 document, which states that only `DEMINDLHENGS` is active and that the LPG boiler residual capacity is not used. However, I have tried entering `0` and `0.00`, but both were marked incorrect. I also checked the other visible values: - `DEMINDLHENGS` shows natural gas consumption, not LPG. - `DEMRESCKNLPG` refers to residential LPG cooking, not the industrial boiler. Could someone please confirm the expected answer or check whether there may still be an issue with the wording or answer key for Question 2? Thank you very much for your help. ![OSeHO11](https://europe1.discourse-cdn.com/loughborough/original/1X/007fd3040c82edd0a1cfd848265cb818f0e732a0.jpeg) ---

Dear @winwul, could you please try 0 PJ ? ---

Dear Fernando, Thank you for your response. I tried entering **0 PJ** as suggested, but the quiz still cannot be submitted because the system marks Question 2 as **incomplete**. It appears that the quiz field may be treating a zero value as if no answer has been entered. I have attached a screenshot showing the issue. Could you please check the question settings or advise how I should enter a zero value so that the system recognizes it as a completed answer? Thank you very much for your help. ![OSeHO11 No. 2](https://europe1.discourse-cdn.com/loughborough/original/1X/336e2a9ca546977ed4d50a1df9713eac97200a40.jpeg) ![OSeHO11 No. 2 (incomplete)](https://europe1.discourse-cdn.com/loughborough/original/1X/5943f248f3872a84da2d39795a7de1190b81864c.jpeg) ---

Dear @winwul, I believe there is an issue with the configuration of the question. I have requested that the quiz be updated to match the latest version. I will keep you posted once the platform has been updated. My apologies for the inconvenience. ---

Stumbled upon the same number but slightly different problem. Here I inserted 48.75 for the value but marked as wrong (have tried 41.25 too, but still marked as wrong answer). For reference, this is the result that I got (pic 2). Thank you in advance for the assistance and support. ![gambar](https://europe1.discourse-cdn.com/loughborough/original/1X/77c564337db24f1cfea76bed1c0a7df1d9b36bc9.png) ![gambar](https://europe1.discourse-cdn.com/loughborough/original/1X/d21ba93c524812410f28c9046107c9cc87bcbb1e.png) ---

Dear @Amarfr, it should be rounded to nearest whole number, have you tried 49?
