spry script error

[ssfhlcommish]

I am new to spry and am creating a webpage with multiple spry tables on it. I got the first table in and it works fine, but when I went to add the second table I receive this error: I included the portion of the script file that it says is causing the error and have italicized the line where it says the error is occuring.
while executing onClick in InsertSpryDataTable.htm, the following JavaScript error(s) occurred:
At line 1445 of the file "C:\Program Files\Adobe\Adobe Dreamweaver CS3\Configuration\Common\Scripts\spry_ajax_utils.j s": offsetstoNode: Argument number 1 is invalid.

function ajaxUtils_promptForSpryRegion(codeOffsets)
{
var bAddSpryRegion = false;
var bIsInsideSpryRegion = false;
var aDOM = dw.getDocumentDOM();
if (aDOM)
{
var origStartOffset = -1;
var origEndOffset = -1;
if (codeOffsets)
{
origStartOffset = codeOffsets.startoffset;
origEndOffset = codeOffsets.endoffset;
}
else
{
var selection = aDOM.getSelection();
origStartOffset = selection[0];
origEndOffset = selection[1];
}
[B][I]var currNode = aDOM.offsetsToNode(origStartOffset,origEndOffset);[/I][/B]
if (currNode != null)
{
var aParentNode = currNode;

Thanks in advance for your help.
