mathscript node errors due to not being able to find .m files

[umars]

I recently installed LV 8.5.1 and tried to open a VI with a mathscript node (originally created with LV 8.2).  It got a broken arrow due to an unrecognized symbol in the node which was the name of a matscript function in a .m file of the same name.  And this worked fine with 8.2.  I updated the mathscript: search paths 'Working Directory' both in the mathscript window and the main app Tools->Options list.  I exited and re-started, but to no avail.  And I made sure to add it as a 'recursive' search folder, even though my file is right at the top.

What am I doing wrong?

Extra bit of info I just found out:  If I open up the VI by itself, it works.  I see the issue only if I open it up from within the project window.

Hello Umars,

In LabVIEW 8.5 you won't be able to use user defined functions if you are you using a Base Package.  Regardless of which package you are using you may find the LabVIEW help file informative.
