[SOLVED] if statement

[adam291086]

I have this If statement

if(incrementH < ImgHeight)
	{   
	document.getElementById('outerImageContainer').style.height = incrementH +"px";
	incrementH = incrementH + 10;
	setTimeout("boxheight()",20);
}

 

Img is set to == the height of the image height. I know it has a value as when i alert(imgHeight) i get 1600.

 

At the moment when i run the if statement nothing happens. If i replace ImgHeight with 1600 then everything works. How can i make this work with the variable ImgHeigh
