Go to Layout [ original layout ]
Enter Find Mode 
Set Field [ TABLE::Kollad ; "==J" ]
Set Error Capture [ On ]
Perform Find 
Set Error Capture [ Off ]
In FileMaker, Layout sets the context, so be sure you go to a layout based on the table you need to search from.
Also, just to search where anything begins with J in Kollad, just put a J in there. The == part means exactly equals too. FileMaker loosely does finds unless you specify exact, which is the opposite of SQL where you have to do LIKE for loose finds.
Thanks for the effort Taylor.
Very difficult to implement as FM has decided that my scripts MUST be in swedish!!!
And I am not sure what the corresponding command to "Enter Find Mode" would be in swedish? (the other suggestions You had, I think I have found the corresponding swedish commands to)
If You use the menu to the right of the scriptwindow my 6:th chapter would be "posts/recs" and the 1:st subselection there would be "ny sökpost". What "chapter" and what subitem is "Enter Find Mode" in the english version of FM You use, perhaps I can find the corresponding command that way?
I REALLY hate when a company wants to be helpful and hasnt thought their "helpfulness" through... in this case that I cant use Your english commands, cos FM decided my native language would be so much better....
