You're absolutely right. Sorry Ted. I believe the expression is 'one brick short of a tower block' !!! Although that might be wrong also. !!
However, I'll look through all my stuff again, (probably in the wee small hours of the morning, as opposed to the cool cool cool of the evening), and I might very well come across something that will help you.
The only thing that will help me is, I suspect, more of the stuff I had prior to posting my previous message to you. Another pint of beer. Hic. Cheers.
