ActionScript V2 help needed

I’m using the AS below which works with AS V1 - no problem!

thum1:scale_target = “100”;
thum1:x_target = “51”;
thum1:y_target = “112”;

But this doesn’t work on V2 with Flash player 8. I get this error message. anyone can help please?

Error Scene=Scene 1, layer=m action, frame=1:Line 1: Syntax error.
thum1:scale_target = “100”;

Total ActionScript Errors: 1 Reported Errors: 1

Thanks
