Hello everyone I have a problem with the additional fields, but I do not know if I'm wrong something, I explain my problem, I have 7 items with the name of the week and for each item I created an additional field for each hour of the day, then 24 but in the frontend, you do not see all 24 but only 12, is a problem of the limit k2 or I'm wrong, please let help me.

It depends how are the extrafields are rendered in your template.
If they are rendered individually then you need to manually render them.

Use as a template joomla 3.3.6 and use of radiowave nuevvo, which has a schedule, by necessity I had to double the extra fields, thank you in advance for your help

Thanks a lot for your hint, I had to modify the array in the template, now works thanks

You 're welcome :)
Although these issues belong to Nuevvo's forum.
