Multiple checks in 'if' condition

HI

I have four tags

 

switch1_running        ''if its running its value is 1..

switch2_running        ''if its running its value is 1..

switch1_value

switch2_value

 

 

 

 

Now, I am checking something like that, which didn comeup correct.

 

if (('switch1_running'=1 and 'switch1_value'  >2 )  or ('switch2_running'=1 and 'switch2_value' >2 )) then 0 else 1

 

1- In my case if only one switch can be running at a time then 

I am first checking if its running, then checking whats the value of it right now. It shouldnt have to be more than 2. Am I doing it properly?. Or is there any VBA built in equation which can help me more here?

2- More on that, I want to write in display, if switch1=1 then "switch1" and if switch2= then "switch2" and if both are running it should write "both".... I am not sure how I can do that, becuase it might involve elseif?
 

 

Thankalot
