Weird if/else error

when i do this:

Code:

for(s=0; s<full; s++)
						{
							if((int)abs((ident[s].top/ident[s].bottom) - (tempIDTop/tempIDBottom)) < value);
							{
								value = (int)abs((ident[s].top/ident[s].bottom) - (tempIDTop/tempIDBottom));
								positionID = s;
							}
							
															
						}

It works.
But if i add an else like this it doesnt work:

Code:

for(s=0; s<full; s++)
						{
							if((int)abs((ident[s].top/ident[s].bottom) - (tempIDTop/tempIDBottom)) < value);
							{
								value = (int)abs((ident[s].top/ident[s].bottom) - (tempIDTop/tempIDBottom));
								positionID = s;
							}
							else
							{
								printf("%d\n", (int)abs((ident[s].top/ident[s].bottom) - (tempIDTop/tempIDBottom)));
							}								
						}

I get this error:

Code:

process.c:266: error: ‘else’ without a previous ‘if’

Line 266 is the line starting with else.

Code:

if((int)abs((ident[s].top/ident[s].bottom) - (tempIDTop/tempIDBottom)) < value);

Quzah.

ah of course, dont know why it didnt complain before
Thanks

Because it is legal to have an if block that does nothing.
