Hi,
this is because you have not found the
Mathematica Book AND the online help
or you may not be able to read the
Mathematica Book OR the online help
You many mean
a=1;
Table[If[x1>a && x2<a,0,1],{x1,0,2},{x2,0,2}]
or
a=1;
Table[If[x1>a || x2<a,0,1],{x1,0,2},{x2,0,2}]
and Equal[] is "==" and not Set[] "="
a=1;
Table[If[x==a,0,1],{x,0,2}]
Regards
Jens
