Thanks for the help otherwise the stuffs might ended up in garbage bin.
I can sleep well tonight.
Glad it’s finally working.

}@gemandze please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:
