I must be missing something here.
In a FileMaker Script, Open File can only open another FileMaker File, not a file created by another application.
So how exactly are you opening this file?
Oops! You are so right ... I use Open Url to open the document
I solved my own problem (after hours and hours) hopefully this post will be helpful to someone.
I am trying to get a FM Pro script to open a Word Template (dotx) as a Word Document (docx). Here is my resolution:
Simply stated, my script has one element using the, "Send Event". In the Send Event options I chose "Send the 'open document/application' message and chose the "Text" option.
In the Send Event Text box I input, "winword.exe /t"S:\Program Specific\VIP Information Packet\templatename.dotx"
1. be sure to put a space after .exe
2. be sure there is NO space after the /t (the /t is a Word switch instructing word to open as a docx)
3. I use an "S" drive, you may be using your "C" drive (If you use the "C" drive I think your path slashes will go the other direction, i.e., "/t"C/Program Specifice/ Vip ..." Further, your path name will certainly be different)
4. "templatename.dotx" is your template name
See screenshot :)
