I can see that I am seriously out of my depth with this and need to start from some other point! Basically, I don't have a picture of where the various bits of code relate to one another: takes information, gives information etc. But still, thanks for the various bits of code. Beginning to know what one does not know is a good place to start on a project!
Is this your first post in this Thread?
I would be happy to help if you explain in more detail what you are having trouble with.
If your question is connected to another Thread about your project it may be better to deal with your question there - if you provide a link to it.
