Lots of hubbub. You have to love this community.


Back to work just a little, since we are trying to learn livecode. Do you see 
how a function, whether mine or not, would be used ubiquitously in your project 
to format fields to display a dollar sign? 


put "$" & goodNumber(field 1) + goodNumber(field 2) into field 3


This handles all data as strings, managing them robustly. The function can be 
placed in the stack script, so it can be called from anywhere. It is your job, 
of course, to remember to do so.


It occurs to me we need the "-" symbol as well. Can you write a handler that 
incorporates that in the right way? Please try, and write back often if you get 
stuck. As another exercise, can you write a more compact function that does the 
same thing? something along the lines of:


put newGoodNumber,(field 1,field 2) into field 3


or a custom command:


addCurrency field 1,field 2,field 3


This sort of exercise is essential to your moving forward. I would agree with 
Jacque's six week timeframe to get over the hump, but I would insist that 80% 
of that time be spent playing with your own stacks, not reading stuff. And 
remember, as others have also said, this is not a software package that you 
learn to use. It is a toolchest, the tools of which you must practice with to 
be able to use. I believe you must make a few stacks, of whatever kind. They 
cannot be so simple that you will not tear your hair out perfecting them. You 
are no longer a user. You are a developer.
