form name not found on asp.net page

[texas1992]

I have an asp.net page that I put some javascript on using the following code:

        If (Not ClientScript.IsClientScriptBlockRegistered("clientScript")) Then
            ClientScript.RegisterClientScriptBlock(Me.GetType(), "clientscript", sScript)
        End If

The code gets put inside the <form> tags but when I run the code I get an error that says that "formFloorPlan is undefined"

          <form name="ctl00" method="POST" action="FloorMgr_Cleaned.aspx" id="ctl00">
<div>
Image goes here
</div>

<script language=javascript type="text/javascript"> 
showStatus('Saving Locations...');
//Update points for every floor object
document.body.style.cursor = "wait";
IDs = new Array();
xLocations = new Array();
yLocations = new Array();
                         
for(x=0;x<document.all.length;x++)
{
test = new String(document.all(x).id);
if(test.indexOf("FloorObject_") != -1)
{
//We must store only UNSCALED coordinates!  Meaning:  Divide by the scale factor before storing
xpos = document.all(x).style.posLeft / formFloorPlan.scalefactor.value;      
ypos = document.all(x).style.posTop / formFloorPlan.scalefactor.value;
IDs[IDs.length] = test.substr(12);
xLocations[xLocations.length] = xpos;
yLocations[yLocations.length] = ypos;
}
}
formFloorPlan.objectIDs.value = IDs.toString();
formFloorPlan.objectXlocations.value = xLocations.toString();
formFloorPlan.objectYlocations.value = yLocations.toString();
/////////////////  LocationCodes (roomcodes) Handling ////////////

Why is it not defined?

Thanks.

formFloorPlan.objectIDs.value = IDs.toString();
formFloorPlan.objectXlocations.value = xLocations.toString();
formFloorPlan.objectYlocations.value = yLocations.toString();

that's first time you call formFloorPlan and that's probably fire this error

there is no formFloorPlan = 'something' so it's undefined

secondly, you shouldn't keep js inside form
