Conditionally resize images - error

Question

I am trying to conditionally resize images based on their pixel range but when I run my script all my images are sizing down to 900 pixels, regardless of size.
I think my conditional is incorrectly written,  can someone help me out
Thanks!

var  doc=activeDocument;
if (doc.width > doc.height)  {doc.resizeImage(newImgSize, null, null, ResampleMethod.BICUBICSHARPER);}
if (doc.width < doc.height)  {doc.resizeImage(null, newImgSize, null,ResampleMethod.BICUBICSHARPER);}
if (doc.width == doc.height)  {doc.resizeImage(newImgSize, newImgSize, null,  ResampleMethod.BICUBICSHARPER);}
var doc =  app.activeDocument;
if (parseInt(doc.height,  10) > '1200px') {fitImage (1800,300);}
else if  (parseInt(doc.width, 10) > '1200px') {fitImage (1800,300);}
else  {fitImage (900,300);}

Problems with UnitValues. Try this to get the conditional part right:
if (doc.height.as("px")   > 1200) {fitImage
(1800,300);}
else
if  (doc.width.as("px") > 1200) {fitImage (1800,300);}
else 
{fitImage (900,300);}
