Hi i have a url "http://mysite.com/images_list?primaryID=11109&instructionID=11110" how do i display the values for primaryID, instructionID in the lister page? Thanks 
You can't print GET variables inside a page in Matrix unless you are using version 3.18.3.
EDIT: changed CAN to CANT 
Functionality to do this was only added very recently to Matrix. In fact, it is only in v3.18.3 that was released yesterday.
(I think Greg means "can't" instead of "can").
Oh… I am using v3.16.1… I tried adding php code in my design. then it showed but my problem is the delete function in ajax is not working in mozilla… 
Adding PHP code in your design is not a viable solution because we have already taken steps to remove that functionality in later 3.16 versions.
If you are just wanting to grab values from the query string, you can easily do this with javascript. 
Yes i did it using javascript.
