Trouble with Displaying Button

Here is some more info:

I have a line item applied to each vehicle called "PAYOFF_PER". This is calculated by taking the field "TOTAL_PAYOFF" and dividing it by the number of vehicles sold ("SOLD_COUNT").

Let's say TOTAL_PAYOFF is $5,000.00 and I'm selling 3 vehicles, making PAYOFF_PER 1,666.67 (rounded up). As 1,666.67 * 3 = 5,000.01, I want to alert the user here that the first vehicle will reflect a 1 cent deduction on the Payoff line.

The function in question is called from a validation script of PAYOFF_PER:

var total = this.getField("TOTAL_PAYOFF").value; // in this example: $5,000
var per = this.getField("PAYOFF_PER").value; // in this example: $1,666.6666666666(repeating)
warning(total,per);

Now the function (document level script) which *should* display button ("WARNING_PAYOFF_PER").

function warning(TotalField,PerField)
{
var PerName = event.target.name // in this example: PAYOFF_PER
var PerRounded = round(PerField,2); // in this example: 1,666.67 
var Count = this.getField("SOLD_COUNT").value; // in this example: 3
var Offset = PerRounded * Count; // in this example: 5,000.01
if ((Offset == TotalField) || (Offset == 0)) // in this example: TotalField = 5,000.00, Offset = 5,000.01
this.getField("WARNING_" + PerName).display = display.hidden
else
this.getField("WARNING_" + PerName).display = display.visible
}

I want the button to appear only when TotalField does not equal Offset. If the are equal, or if there is nothing entered it should be hidden. For some reason I am getting the opposite.

Thanks again!
