It's going to take some time for me to work through your contribution and I look forward to the experience. I'm grateful for your offer to provide some further tuition and I will probably take you up on that once I have paused to consider what it is about this particular form of OOP that I find so difficult to get my head round. I do know that I find the move from VFP to MS Office is not straight forward. VFP also had Properties and Methods but in VFP methods were realy more akin to functions which were written by the programmer. I'll be back later once I have taken stock. Many thanks
