Error message present even if the compilation is correct

When I verify a sketch , I see an error . Then , when I correct it , the red line is still there(I tried verify again) .

Hi hyzaoia

Just going to ask you to read through this so that you can add additional information as right now there is not much to go on.

Hi @hyzaoia,
can I see a screenshot or can you give me exact steps to reproduce?
Thanks

It would be great if you could share with us also the URL of your sketch, thanks!
