getting plugins working?

i have a .OBJ pyton script importer/exporter for blender 2.23 but after following the instuctions and pressing alt-p nothing happens, can some one tell me the proper way of using them

thanks

Have you pressed alt-P while the cursor is on the python editor?
I assume you loaded the script in the integrated python editor…
What error messages do you see on the blender console?

when i run the script in the console it says something about the variable ‘OS’ is undefind.

ive found the problem, windows98. i can run the script on a xp box but not on win98.
has any one else had this problem, or know how to fix it?

did you define your PythonPath correctly in Blender?

There’s may ways to define your path, so I suggest you should make a search in this forum for all the things you should do to make it work.
