Checkbox not available in ASP.NET page

[lightgram]

Hi

I need to reset the position of a checkbox in my ASP.NET page.

The checkbox is defined:

<asp:CheckBox  TextAlign=left  ID="CheckBox2" Style="z-index: 203; left: 538px; position: absolute; top: 144px;" Text="Test CKBOX" 
   runat="server" />

In the script when the page loads I have the following code that recalculates the left position:

document.getElementById("CheckBox2").style.left =  parseInt(document.getElementById("CheckBox2").style.left) + document.getElementById("dvSpacer").style.posWidth; 

However this produces an 'Invalid argument' error. The same line of code works for my other controls on this page but not this one. Does anyone please have any idea what I am doing wrong.

Thanks in advance.

posWidth is non-standard. Use width instead. Can you give some example values.
