navigation question

hi all,
i need to add a BACK button to some reports.

I have a report that has a hyperlink to another report. When I click it, I go to that other report, but because I cannot open it into a new page, I got to be able to return somehow to the initial page. In this second report I added a row, I have embedded the picture of a button that reads GOBACK, but for the Navigation property I do not know how to specify navigation to the previous page.

Anybody, any ideas?
thanks,
kowalskyTry javascript:history.go(-1) for a url-based parameter|||Thanks for the tip.

Could you be a littel more specific, though? I don't understand what you mean: what is the synthax for the javascript code? where do i create the url-based parameter?
Right now my second report is already based on a parameter (but this doen't help).
The place where I should try to insert the javascript is probably the Hyperlink action section in the Navigation tab in the button's properties.
Am I close?

Thanks,

I haven't tested this, but you should be able to create a new textbox, and under advanced properties add the javascript in the URL navigation section. It should be something like javascript:history.go(-1) to go back a page.
Another solution may be to create a bookmark link with a reference to the page number property.
