I wonder is it possible to use AND in "Case" or "Switch" statement. I am keep getting error.

I need to do switch if value of two tags turns to 1 and 6:  
for example:  
"when MachineMode=1 and tag2=6 turns defined tag to 3 etc.  
see below  
Switch ({[.]../MachineStatus/MachineMode},1 && tag2=6,0,2,3,4,5,  
3,  
1,  
1,  
2,  
1,  
1,  
1)),0)

No, you cannot. Switch operates on a single input, and the `&&` operator automatically returns a boolean, so you'll only have two possible inputs to your switch (true and false).  
Try to write out the truth table you're aiming for.  
When MachineMode is 1 and Tag2 is 6, the output is what?  
When MachineMode is not 1 and Tag2 is 6, the output is what?  
When MachineMode is 1 and Tag2 is not 6, the output is what?  
When MachineMode is not 1 and Tag2 is not 6, the output is what?

A simple solution:

```auto
case(tag2 * 100 + {[.]../MachineStatus/MachineMode},
    0, "black",
    2, "brown",
    100, "gray",
    102, "yellow",
    206, "blue",
    "white" // default
)

```
