What if I want to get a specific data value from the query I looked up?

I want to go to another retool page as a parameter by putting GT_2022XXXX values ​​in the action button. Can you tell me how to do it?

I would also appreciate it if you could tell me how to pass the selected value to another retool page as another parameter.

In the value for 'URL Query Parameters to add' you can add:

{{ selectUserListTable.selectedRow.data.PlatformID }}

thank you
I registered in the url parameter, how can I get it on the next page?

On the other page you will have access to the URL parameters via:

urlparams.PlatformID

You can then just put this value in your Query on the detail page like:

SELECT *
FROM Platform
WHERE PlatformID = {{ urlparams.PlatformID }}

thank you!
