Not able to call popup window twice in a page

[MarFur93]

In my \[code\]ASP.NET\[/code\] application, I have been working on a page in it,I wrote a \[code\]javascript\[/code\] \[code\]script\[/code\] for showing a popup window when a \[code\]link button\[/code\] is clicked now I am in need of another popup window in the same page when a \[code\]button\[/code\] is clicked but the problem is that if I call the \[code\]script manager\[/code\] for the \[code\]button\[/code\] it gives the output of the previous opened popup window(when \[code\]link button\[/code\] was clicked)
