HI

Thanks a lot for ur help. The problem is solved and it is running on both IE and Mozilla FireFox.

I just replaced the line

Set oExcelChart = Server.CreateObject( "ExcelChart.application" )

with

Set oExcelChart = Server.CreateObject( "ExcelChart.cExcelChart" )

and it runs fine

now I am trying to make line graph. please provide some help in this regards.

thanks again.
