Thanks for replies

Hi,

Thanks to everyone that posted suggestions. I've managed to sort out the
problem now and its working perfectly.

To Michael Kay,

It's the first time I've registered with any list, or posted a problem.
Therefore, I apologise for the mistakes I've made. I was also in a hurry
to complete the project;I'll try and be more careful in the future
though.

Thanks again everyone.
