Excel To HTML - Auto Publish With File Update

Im trying to use excel as part of an real time display system, what im looking to do is after xx time period import some data (which is fine, I have that bit sorted), then save to as html- (hopefully using excel 07 abilty to repubish data to update the same file with more info).

I have added some Javascript to the html file to auto scroll, and then will be adding a refresh script which should hopefully update the display with any new info genrated from excel...

so far I have found the following code, but could do with a hand to tie it all up!

Code:
Public Sub Watchon()
State = "Mointoring Folder..."
Timerun = Now() + TimeValue("00:10:00")
Application.OnTime Timerun, "DetectNewFiles"
Userform1.Nextupdate.Caption = ">Next Update will be @: (" & Timerun & ")"
With ActiveWorkbook.PublishObjects.Add(xlSourceSheet, _

[code]....

Then within DetectNewFiles Sub, I need to update the html data, I guess I can't reuse the above bit, as it would just overwirte the whole file (and so remove javascripts too).

Code:
Sub DetectNewFiles
'Some code to import text files to excel
With ActiveWorkbook.PublishObjects("Book1_24990")
.Publish (False)
.AutoRepublish = True
End With

Some code to reset next time update of DetectNewFiles
