1. HELP! I'm stupid.... novice "wanna be" or trying to be...

Programmer. I'm also into making wine and mead. I'm trying to write a very
simple program to convert the cc's of sodium hydroxide used to the % of 
tartaric acid and the parts per thousand of sulfuric acid. But, I don't know 
what i'm doing. I just play with computers. Can some one help me solve this 
problem? The problem is that,  besides a few bugs that need to be worked
out, "I can do it!", I don't know how to multiply the information in the 
editText box with the other part of the formula. By viewing the code i'm sure
that someone will either say i'm a complete idiot, or think that i'm doing ok
for a newbee and help me with the simplist solution to this problem. Here's 
the code:

I think the problem is in the procedure convert_CCSHTS(), i guess? I'm sure
there could be a simpler code to write this program, it's just that I don't 
know it. Can anyone recommend a good book on this type of programming that I 
could get to help me become a better programmer? Any help will be much 
appreciated. Thank you.

Peace,
Bill

Try:

setText(PTAAnswer, sprintf("%3.2f",getNumber(CCSH)*tartaric))
setText(PPTSAAnswer, sprintf("%3.2f",getNumber(CCSH)*sulfuric))

I got your message. I had tried using setHandler on my first attempt, and 
that was the code I wanted to use, but I had problems with it, so I went the
other route. I will try your code and if it works I will add your name to the 
new program. Thank you very much...
