executeProgram to open pdf

This should be an easy question.

I have a field with filename of pdf file, I need user be able to click on the filename and the file would open in acrobat reader.

I tried this, just to oper the acrobat reader:

application.executeProgram(‘/Applications/Acrobat Reader 5.0’);

but it comes up with ‘Couldn’t open the file message’.
I’m on OSX and the path to acrobat reader is as in the command above

Thank you
