Thanks so much for your response. I now have each of my three checkboxes using the following code:
private void chkEnergyBooster_CheckedChanged(object sender, EventArgs e)
{
decimal subtotal = 0.0M;
subtotal += chkEnergyBooster.Checked ? .25m : -0.25m;

lblSubTotal.Text = subtotal.ToString("c");
}

But, I have a few problems. The first is, when I check multiple boxes, the number in lblSubtotal does not go from .25 to .50 to .75. It just stays at .25 no matter how many boxes I check. How do I get it to increase from .25?

The other issue is that when I check and uncheck a box, the label goes from $0.25 to ($0.25) and I am not sure why.

Also, I have a lot of functions that use the variable "subtotal" in other parts of my form. How do I maintain that variable's value throughout the form? It seems like the way I have it now, it just exists within these checkboxes.checkchanged events.
Thanks!
