Thank you for looking.
Well there is good news and bad news.
I deleted my child theme and started again. All I have in my child folder now is the style sheet. AND my theme now has all the possible customizations through the dashboard that I have in my parent theme.
So, all the customization I did ( and it was not a lot) is being picked up. The bad news is, the css to the new style sheet is not being picked up.
I have pasted my css file here but I am calling it a day.
Thanks so much. Not sure if this topic is finished as I have not been able to do what I asked about to begin with, but at least I have made some progress!
