I would love to get some advise.

Then please post your code correctly using code tabs.
Copy your code in the IDE.
Press the </> icon at the right of the reply box, and paste your code between the code tabs that come up.

That is what Tom in reply #3 is telling you.

If you can't manage that then it is doubtful if you can benefit from any advice we can give you. Show you care by helping us to help you. Look at your code you posted in the original post. Is that what you posted? Does your code change into italics part way down?
