Asp.Net - Changing number format to display just a value, regardless of negative or positive.

This is a two part question, so I will post the first one...

I have an output where the number is formatted in a currency, and when the value is negative, parenthesis are placed around the asp label that displays the value of the text.  Here is the label tag :

<asp:label id="lblIncreaseInAmountContributingTo401k" runat="server"/>
___________________________________________________________________________
And here is the code where it is called, computed, and formated, I have broken up the code and listed it in order, as I am not sure how far back it is needed to go to aquire the desired result, but this should be enough :

1)

lblIncreaseInAmountContributingTo401k.text = FormatCurrency(Cdbl(hiddenIncreaseInAmountContributingTo401k.text))

____________________________________________________________________________
2)

<asp:label id="hiddenIncreaseInAmountContributingTo401k" runat="server"/>

____________________________________________________________________________
3)

hiddenIncreaseInAmountContributingTo401k.text = Cdbl(hiddenFutureContributionAmount.text) - Cdbl(hiddenCurrentContributionAmount.text)

I am a beginner trying to learn, so thank you for your patience as I learn how to post in the most effective way
