Does any one know what this is referring to:

I have a database hosted through IWP and I have tested it on various
machines xp win 2000 with IE 6 and 7, and all have been fine.

but one of my clients has been getting an error on opening the database and
trying to click into a field

'A runtime error has occurred'
'Do you wish to debug'

'line 51'
'Error: object expected'


does any one know why this is happening?

the client in question is running
win2000 with IE 6.0.28

although I have tested it on a similar setup and it worked fine

Thanks for any help
