setmetadata

System

Hi
I am working on a custom menu CGI script. User can select a file in the Teamsite UI and select "Set EA" from File menu. This CGI menu item gets the existing EA for that file and also compiles a presentation template that spits out an HTML Metadatacapture form which contains fields pre-populated with the existing metadata on the selected file. User can add more metadata for the file.
My problem is when the user adds additional metadata and clicks submit , i post this form data to another CGI. But i am unable to get the form values in the CGI. I am using POST method.
Can i use iwsetmetadata.cgi to set the form metadata values to the file?
Or is there any other alternative way of achieving this?
Any help in this regards is highly appreciated.
Thanks.
