Changing textbox color

[holly]

Hi

how do i change the color of my textbox via ASP?

The code I have is

<tr> 
            <td class="formText">Weight Tolerance Plus</td>
            <td>
                <input type="text" disabled name="weight_tolerance_plus" maxlength=10 size=20
                value='111' onChange="changeFont(this);">
            </td>
            <td nowrap class="formText">Maximum Pallet Weight</td>
            <td>
                <input type="text" name="maximum_pallet_weight" maxlength=10 size=20
                value='735' onChange="changeFont(this);">
            </td>
          </tr>
          <tr>
