Thanks for the reply but even after changing the order things are not working as required.

One thing which I found out is that this problem occures only when the data file i.e. excel file is a big say around 2500 rows if I reduce this to 1000 rows everything works fine, there is no excel object in the memory.

So is there any problem in working with large excel file.My system config is windows 98,256 MB RAM

Thanks in advance
