Thank you for getting back to me and for your assistance.
You have managed to be a great help with your answers.
I tested my site going online to index.php and was relieved to find all the CMS inplace.
The holding page index file was also the problem as you surmised. By going into Cpanel I was able to remove it and upload the current index page for my full site.
Today I have been able to progress with setting up the MySql database requirments. I can
now see my site online and have access to the CMS on my computer. I am now editing my site accordingly as 'work in progress'
Thank you again for your help.
