Hello
I am trying to import a parameter through MATLAB within a GDX file.

$GDXIN 'data.gdx'
Set
   bus        / 1*14   /
   slack(bus) / 1     /
parameter
Inc(*,*);
$load Inc
$GDXIN

I get the error (error 492): Symbol not in GDX
While I have a parameter named Inc in data.gdx file as shown below.

what is wrong here?
It is worth mentioning there is not any problem with importing the set shown in the GDX file

The GDX file is not so large. Perhaps you could attach it.
