Improving performance of scripts in a PDF form

Question

Hello there.  I'm a bit new to the scripting in Acrobat and find myself with a complex form that has a number of instances (about 70)  of the following script (specific to individual fields):
event.value=this.getField("Ranks").value + this.getField("Mod").value + this.getField("MiscMod").value;
var trained = "Untrained";
var skill = "Ranks";
if ( (this.getField(trained).value != "On" ) && (this.getField(skill).value < 1)) {
event.target.textColor = ["G", 1]; }
else {event.target.textColor = ["G", 0];}
The code works fine, but with this many instances, performance of form is sluggish while updating. In addition, there are approximately 200 simple addtion fields being used.
I'm looking for any advice, scripting or otherwise, to help improve performance.
Thanks so much in advance.

If you create a function in the document scripts :
function updateField() {
event.value=this.getField("Ranks").value + this.getField("Mod").value + this.getField("MiscMod").value;
var trained = "Untrained";
var skill = "Ranks";
if ( (this.getField(trained).value != "On" ) && (this.getField(skill).value < 1)) {
event.target.textColor = ["G", 1]; }
else {event.target.textColor = ["G", 0];}
you could replace the code in each field with the following function call, and they would all use the same code:
updateField()
Without knowing exactly what 'slightly different code'' entails, you can add parameters to the function call:
function updateField(Rank, Mod, MiscMod) {
event.value= Rank + Mod + MiscMod;
var trained = "Untrained";
var skill = "Ranks";
if ( (this.getField(trained).value != "On" ) && (this.getField(skill).value < 1)) {
event.target.textColor = ["G", 1]; }
else {event.target.textColor = ["G", 0];}
and you could call it in each field with different values for 'Rank', 'Mod', and 'MiscMod' (or whatever parameters you use) like this:
updateField(getField("Ranks").value, this.getField("Mod").value, this.getField("MiscMod").value )
or
updateField(getField("aDifferentRanks").value, this.getField("aDifferentMod").value, this.getField("aDifferentMiscMod").value )
or
updateField(47, 12, 45)
If you need to make changes, you only need to change the 'updateField' function once, and any field which calls it will use the updated code.
