David,
That worked WONDERFUL! With just a couple of tweaks I was able to have it
do exactly what I wanted. Having no javascript training, this forum is
invaluable to me. I always try to google my questions before I post, but
sometimes there's too much info out there and when I post in the forum
your replies make it much easier for me to understand, everyones help is
greatly appreciated.

Subject: [fusionpro] RE: RGB to Hex rule
Lisa,
I don't know if you are passing the RGB value as one specific field
(255,255,255) or as three separate fields. But I found this script on a
website when I googled RGB to Hex conversions and it works. You can place
this entirely into one rule, or you could put the function part into the
JavaScript Globals section and call it from different rules.
function toHex(N) {
if (N==null) {
return "00";
}
else {
N=parseInt(N);
if (N==0 || isNaN(N)) {
return "00";
}
else {
N=Math.max(0,N);
N=Math.min(N,255);
N=Math.round(N);
return "0123456789ABCDEF".charAt((N-N%16)/16) +
"0123456789ABCDEF".charAt(N%16);
}
}
}
var h1 = toHex(Field("R"));
var h2 = toHex(Field("G"));
var h3 = toHex(Field("B"));
return h1+h2+h3;
.....
If you are using three fields for the R G and B values then you could use
this rule almost verbatim. If you are using one field to pass all three
values then you need to break it up into individual values before you call
your functions.
Cool thing about this rule is that even if a blank value is passed, the
rule will value that as if it were a "0" instead of a blank.
Good luck,

Subject: [fusionpro] RGB to Hex rule
Hi, Could someone help me out with a rule----
If Red = 255 return FF
If Green = 255 return FF
If Blue = 255 return FF
Then combine Red Green Blue to = FFFFFF
Which by itself isn’t a hard rule, but I need to incorporate the whole 256
possibilities of RGB. The client is sending in Data in RGB and from what
I’ve read I need the Hex equivalent to make it work. I’ve made an external
data file with RGB Values in col1 and the Hex equivalent in col2, I don’t
know how to incorporate that into a rule or if it’s even needed. Any help
would be appreciated.
