In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

Variable from the sum of two variables

Hi folks, I'm learning MEL and having trouble understating what's going on here.

I'm trying to get a variable from the sum of another two variables defined by object attributes, for example:

float $scaleY = `getAttr "pCube1.scaleY"`;
float $scaleX = `getAttr "pCube1.scaleX"`;
float $sum = ($scaleY + $scaleX);
print $sum;

This gives me the correct result, but I'm getting this warning:

// Warning: float $scaleX = `getAttr "pCube1.scaleX"`; //
// Warning: Line 2.42 : Redeclaration of variable "$scaleX" shadows previous declaration at line 1. Previous value will be overwritten by explicit initializer. //

Where exactly I'm redeclaring variable $scaleX? Is the syntax wrong? If anyone have any suggestions it would be highly appreciated. Thanks!
