I agree with you @JMichaelTX , thanks for explaining the substring useage too.
It is only now I am starting to see what I am supposed to do in the variable dialogue box. You create a label really? I realize as well that if you name every variable the same, and I think you are right I think I was doing that at one point, you might get conflicts. I got that you were supposed to enter something of your own in some way in time. Even then it was confusing.
Then I was trying things like "VarPhone" and thinking it was supposed to 'set' something elsewhere or something. I said to Peter I would keep a record of the learning experience. It is very hard to do though, once the fog lifts things look clear ironically.
"VarName" looks to me like a function in some way in other words. Now I am sure it doesn't look that way to modern IT folk, but there you go. It looks to me intuitively, and I still find it hard to shake off, like (2x) would in a math formula. Do you see what I mean?
