I tried placing this at the top of the program:

#define TITLE skill7

I then replaced:

title = "OGRE"; // in the ogre_action() function
and
title = "WIZARD"; // in the wizard_action() function

with:

my.TITLE = "OGRE"; // in the ogre_action() function
and
my.TITLE = "WIZARD"; // in the wizard_action() function

and I changed the TEXT function to look like this:

Code:
TEXT* enemy_health_txt =
{
	layer = 1;
	pos_x = 830;
	pos_y = 10;
	string (my.TITLE, "'S HEALTH:");
	flags = CENTER_X | TRANSLUCENT | SHOW;
}


I am now getting this error:

Error in 'line 1298:

< my.TITLE = "OGRE"; >
.
Error in 'line 1664:
