Checkbox in Interactive Grid

I downloaded the application 261 with a test checkbox (page 11) with the .js and .css files.

Works fine.

Now I tried to copy the page for my application, changes the columnname in the select statement to DONE, the column content from J to Y.

select LOTP_ID,

LOTP_NAME_KURZ,

LOTP_NAME_LANG,

case when LOTP_GKZ = 'J' then 'Y'

else 'N'

end as DONE,

LOTP_DGV,

LOTP_DGB,

LOTP_DLA,

LOTP_BEN,

LOTP_INFO

from lotp;

copied the page Javascript and CSS, copied the css class and Javascript Initialisierungscode.

I only see an empty checkbox and cannot change (from select statement the checkbox should be activated) to active or inactive.

Where is my error?

I see the blue tick.

Now I created a new application and copied the page with the checkbox, downloaded and uploaded the shared components . It doesn't work.

I am not so familiar with css an js scripts so I left both unchanged

Please help me again

I copied your help into page CSS inline but how can I call it from DONE (checkbox) column?
