How to show field from – Advance custom fields?

I found the infomration:

custom_field-[Name] – The value of a post or page’s custom field. If you had a custom field “Foo”, you would use the following as the hidden field value: custom_field-Foo

But, I am not using “wordpress custom fileds”, but “Advanced Custom Fields“

It is possible to link field and sub field? For examplet how to link those two fields?
<?php the_field(‘ikona’); ?>
<?php the_sub_field(‘prace-subblok-pozice’); ?>

If I use: [hidden pozice “prace-subblok-pozice”] it doesnt work….

Thanks,
Jakub.
