Browser finder in pop up sheet

Just wondering if anyone know how to set the finder location or have the finder loop through this string to go to a location so i can hit the import button in this app?

string: Macintosh HD/users/work/
I broke this down into a list to see if i could loop through it and click on the right button

click button “Machintosh HD” in window 1 etc…

does anyone know how to do something like this??

(Dialog is a pop up sheet)

Model: iMac
Browser: Safari 125
Operating System: Mac OS X (10.4)

no one know how to change the browser location in a popup sheet??
