Clearly Main must be something other than a 3D array at this time or you've aliased size or somesuch.
What does
whos Main
return? If that doesn't clarify things, then
which size
and/or
clear size
and try again.

In addition to dpb's suggestions, which will probably fix it. You got the names wrong. The first dimension returned by size() is the y dimension (rows), not the x dimension. Thinking that the order x,y is the same as row,column is a very common error. So use one of these calls
[rows, columns, numberOfColorChannels] = size(yourImage);
[ySize, xSize, zSize] = size(yourImage);
but NOT the way you did it.

Good catch, didn't even notice that--dpb

Maybe a bit pedantic, but it all depends on your coordinate system. The OP could very well have a coordinate system where x is pointing down and y pointing right.
Probably not.
It's actually a bit of an issue that matlab's documentation (particularly regionprops) doesn't actually specify which coordinate system is in use.
