Hi all - I'm trying to accumulate a total from a value within an array of
structures, but I keep getting a data conversion error. It refuses to
recognize the value as a number, though every indication says it is. This is
the line that's throwing the error (near the bottom below): <cfset thetotal =
thetotal + (session.rec.list)> I don't understand why the value isn't being
seen as a number, and I don't know what I can do to convert it first. Please
help! here's the code:

<cfset thetotal = 0>

<cflock name="lockOutput" timeout="5">
<table width="950" align="center" border="1" bordercolor="silver"
cellpadding="1" cellspacing="0">
<tr>
<td class="leftdetail" width="50"><b>S/O</b></td>
<td class="centerdetail" width="100"><b>Ship Date</b></td>
<td class="centerdetail" width="100"><b>Cust ID</b></td>
<td class="centerdetail" width="100"><b>Cust PO</b></td>
<td class="centerdetail" width="60"><b>Invoice</b></td>
<td class="centerdetail" width="100"><b>Product</b></td>
<td class="centerdetail" width="275"><b>Desc</b></td>
<td class="centerdetail" width="30"><b>Qty</b></td>
