Cfinput=text background color style

Question

I have a CFFORM format=flash and on one of my text boxes I
want the background color of the text box to be either red or green
depending on the value of the text box. If the Balance text box
value is greater than 0, then the background color of the text
input should be red, if it is EQ 0, then the background color
should be green.
Here is a snippet of what I'm trying to do:
<cfsavecontent variable=GreenBkgd>
if(Number(Balance.text) =
'0'){Balance.setStyle('backgroundColor', '##00FF00')}
</cfsavecontent>
<cfinput type="text" name="BeginBalance" value="499.99"
onChange="#GreenBkgd#">
<cfinput type="text" name="amount1" value="0.00"
onChange="#GreenBkgd#">
<cfinput type='text" name="amount2" value="0.00"
onChange="#GreenBkgd#">
<CFSAVECONTENT variable="CalcBalance">
Number(BeginBalance.text) -
Number(amount1.text) -
Number(amount2.text)
</CFSAVECONTENT>
<CFINPUT type="text" name="Balance" label="Unreconciled
Balance" bind="#CalcBalance#" readonly="yes"
style="'backgroundColor', '##FF0000'">
I'm sure there is just something small I've missed, any
guidance would be appreciated!

You could simplify it further to something like:
<cfsavecontent variable="GreenBkgd">
if(Balance.text == 0)Balance.setStyle('backgroundColor',
'0x00FF00');
</cfsavecontent>
<cfsavecontent variable="CalcBalance">
{BeginBalance.text - amount1.text - amount2.text}
</cfsavecontent>
<cfform format="Flash">
<cfinput type="text" name="BeginBalance" value="499.99"
onChange="#GreenBkgd#">
<cfinput type="text" name="amount1" value="0.00"
onChange="#GreenBkgd#">
<cfinput type="text" name="amount2" value="0.00"
onChange="#GreenBkgd#">
<cfinput type="text" name="Balance" bind="#CalcBalance#"
label="Unreconciled Balance" style="backgroundColor: ##FF0000;">
</cfform>
