Hi,

I have 3 php scripts. 

In the first script I have a dropdown box, the user selects an organism from this and clicks submit. This takes him to page2. In the page2.php script, the organism value is set as a session variable. When I print the organism name on page2 after setting it as a session variable, it works fine and shows me the value that the user had choosen on the first page. 

This page2 has a second dropdown where the user chooses a pathway and clicks submit. This takes the user to page3. In the page3.php script, the pathway value is set as a session variable. When I print the pathway value on this page3, it works fine, it shows me the value chosen by the user on page2. But when on this page3 I try to print the organism value, which was chosen on page1 and set as a session variable in page2.php, I don't get its value.

What could be the problem?

I am using session_start() on both page2 and page3.

Expected result:
----------------
I expect to see both the organism name and pathway name on page3 because both are session variables.

Actual result:
--------------
I get the organism name on page2 and pathway name on page3, but I want both organism name and pathway name on page3.
