I have a Opportunity form named opportunity.aspx where Opportunity Name is in the list box and there is a button named Find. In this form, opportunity name is generating at run time in the list box. Here user has to select any opportunity from the list box and has to click on the Find button to find related data for the selected opportunity.
Now I want to use selected opportunity name value( from opportunity.aspx) to another form named details.aspx where I will use this value to find related data so that I can retrive the record. But I am not able to get selected opportunity name from opportunity.aspx to details.aspx

So, how can i do this ? Is there any one who can help me. It's very urgent.
