Problems using logical expressions for "partly-coloured plot"

Hi,
currently I try to deal with a "partly coloured plot" using the element selection mode, located in the general plot parameters.
I already studied the manual where an example for a logical expression is listed. Unfortunately COMSOL replies with an Syntax Error when I try to realize this example.
My intention is to plot a 2D Model where only a part is shown coloured.
For example: 0.1 < x < 0.3 and -0.1 < y < 0.1.
I also studied the logical expressions list in the users manual, without success.
An example:
In my case, plotting the logical expression "x > 0.1" works fine however the expression "x > 0.1 & y > 0.1" replies an error.
Anyone who could help me solving my problem?

Problem solved!
For plotting an coloured area for example: 0.1 < x < 0.3 and 0.1 < y < 0.3 the correct logical expression is as follwed:
x > 0.1 && x < 0.3 && y > 0.1 && y < 0.3
For plotting an coloured area for example: 0.1 < x < 0.3 and 0.1 < y < 0.3 the correct logical expression is as follwed:
x > 0.1 && x < 0.3 && y > 0.1 && y < 0.3
