When this code is executed: window.location.href = "plkfrm.asp?linktypeid=" + this.value ~ it calls another 'get' from the server, this time with the linkttypeid in the URL.
This is the same as if the person had saved that page (with the linktypeid=x in the url at the time when the page was 'saved') to their favorites... and had then executed it.
In your case, the person has added some data and then has selected a value from the listbox, causing the window.location.href code to be executed on the OnChange event.
In order to retain the information the person has already keyed in, you need to perform the following;
Click on the Page containing the ListBox (not on the record - on the page) and from the Properties window select the events tab. Right click on Before Show and select 'Add Code'.
Place the following code within the before_Show block.
Function Page_BeforeShow()
Dim sFName
Dim sLName
sFName = Request.Form("txtFirstName")
sLName = Request.Form("txtLastName")
RecordDataSource.txtFirstName.value = sFName
RecordDataSource.txtLastName.value = sLName
End Function
Do this for each field on the form...
Replace RecordDataSource with the actual name of your datasource.
Now, when the user selects the value from the listbox, the page performs a 'get'. The difference is that now it looks for any values that were on the page when the 'get' was executed and replaces them when the page load back up.

I've tried as below, but it does not work:
before_show()
dim cstationa
dim cstationb
dim cCapacity
dim clinktype
dim cplucount
dim cphylinkno
dim clength
cstationa = Request.Form("stationa")
cstationb = Request.Form("stationb")
cCapacity = Request.Form("capacity")
clinktype = Request.Form("linkype")
cplucount = Request.Form("plucount")
cphylinkno = Request.Form("phylinkno")
clength = Request.Form("length1")
pyphylink1.stationa.value = cstationa
pyphylink1.stationb.value = cstationb
pyphylink1.capacity.value = ccapacity
pyphylink1.linktype.value = clinktype
pyphylink1.plucount.value = cplucount
pyphylink1.phylinkno.value = cphylinkno
pyphylink1.length1.value = clength
