JavaScript Help Needed - How to Show Layers
I am a VB programmer by trade but I've been asked to write a simple DRG calculator in ASP that will work on a variety of browsers. I used Dreamweaver to start so most of my scripts work fine, however, on one page (jCalc.asp) I have three buttons that peform some special functions:
1) Show Calculations - make a layer (layerCalculations) visible that shows the details behind the complex calculations
2) Show Variables - make a layer (layerVariables) visible that shows the variables, their English names and their current values
3) New Calculation - returns user to entry screen
Button #3 works fine. Buttons 1 and 2 do nothing. I added an alert in my function to confirm that I was actually hitting the function which I was - so I know it must be the syntax I am using.
I've tried at least 6 variations in code with the same result. I need a JavaScript soul to tell me what I'm doing wrong!
Here is the code behind my page:
=======================================
<%@LANGUAGE="JAVASCRIPT" CODEPAGE="1252"%>
<%
function formatAsMoney(mnt)
{
mnt -= 0;
mnt = (Math.round(mnt*100))/100;
return (mnt == Math.floor(mnt)) ? mnt + '.00'
: ( (mnt*10 == Math.floor(mnt*10)) ?
mnt + '0' : mnt);
}
%>
<%
// Perform calculations
var LRSA = (rsVariables.Fields.Item("LRSA").Value);
var NLRSA = (rsVariables.Fields.Item("NLRSA").Value);
var WageIndex = (rsVariables.Fields.Item("WAGE_INDEX").Value);
var COLA = (rsVariables.Fields.Item("COLA").Value);
var SFCR = (rsVariables.Fields.Item("SFCR").Value);
var LUAO = (rsVariables.Fields.Item("LUAO").Value);
var GAF = (rsVariables.Fields.Item("WICGRN").Value);
var CAPCOLA = (rsVariables.Fields.Item("COLACP").Value);
var CAPDSH = (rsVariables.Fields.Item("DSHCPG").Value);
var CAPIME = (rsVariables.Fields.Item("TCHCP").Value);
var OPRDSH = (rsVariables.Fields.Item("DSHOPG").Value);
var OPRIME = (rsVariables.Fields.Item("TCHOP").Value);
// Perform TOTAL calculations
var TOP = formatAsMoney(((LRSA * WageIndex) + (NLRSA * COLA)) * DRGWeight * (1 + OPRDSH + OPRIME));
var TCP = formatAsMoney((SFCR * DRGWeight * GAF * LUAO * CAPCOLA) * (1 + CAPDSH + CAPIME));
var TDP = formatAsMoney((((LRSA * WageIndex) + (NLRSA * COLA)) * DRGWeight * (1 + OPRDSH + OPRIME)) + ((SFCR * DRGWeight * GAF * LUAO * CAPCOLA) * (1 + CAPDSH + CAPIME)));

Your help is greatly appreciated!
