How to display an element by if condition liquid

Thank you for your reply and help,

For some reason, is still without working,

I have tried creating a section directly, and it works

But on the current one, is not working.

{%- if section.settings.maintooltip_product != blank -%}  
  

 content here, etc.

{%- endif -%}

maybe should I add bloks?

{%- if section.settings.blocks.maintooltip_product != blank -%} ?

Thank you
