Code that just stops working

Hi folks

It appears to me that people who follow this forum have a different field of interest, and different skills, from mine (which is just programming). My current project has hit a couple of roadblocks, and I am hoping that this appeal might see a couple of you have a look at my issues and see if your interests and skills can provide a solution. Please reply in the other forum as this will make your wisdom available to the audience there.

Any and all assistance will be greatly appreciated.

Please don't crosspost, other post is being deleted. Post once, have some patience.
