Querries are not working in Windows XP

[sheela]

I apologyze for posting for the wrong group. I have
developed a database, which is working fine on
Windows 2000 operating system with ACCESS 2002 and ACCESS
2003.
But the same program is not working on Windows XP using MS
ACCESS 2003.
There are two select querries not working, which take
parameter value. And these querries will be called from a
form.
Could some one tell me what i need to do to make the
database application to work?

Thank you,
sheela.
