open a .xls fine into filemaker

Good afternoon everyone.

I need to open a .xlsx file by pressing a button

I have tried with a script, where I establish a variable
$ filename = e: Works Josram Presup AAVSA slopes 345 7 Apr 14.xlsx

And using the command „Send DDE Execute“
The service name = „c: Program Files Microsoft Office Office16 Excel.exe“

But when you run it, it just does nothing

Can someone tell me that I’m doing wrong?

Thanks in advance

regards

Pedro
