Multiple "AND"'s in select case?

[polymer52]

Does Select case not allow and's in one line?
Here is a snippet.
Even when all is true it ignores the first 2 lines.

Background:
pv = current photovoltaic voltage (varies 0-34v)
pvhigh = voltage to turn on both grid tie inverter and battery charger (13.5v)
pvmin = minimum pv voltage to shut down system (12.0v)
batt = current battery voltage
battmax = maximum battery voltage (13.2v)

Select Case pv			
    Case is >= pvmin and pv >= batt and pv <= battmax			
        gosub ChargeBatt	               'Turns on batt relay                   
	Case is >= battmax and batt >= battmax			
    	gosub gridtie                      'Turns on inverter relay
    case is >=pvhigh                     
        gosub AllSystems                'Turns on both relays
	Case else                          ' < pvmin. Turns off both relays
   	gosub standby
end Select				' Resume here after case is executed

Now if I delete the ands it will jump to the subs.

Select Case pv			
    Case is >= pvmin			
        gosub ChargeBatt	      'Turns on batt relay
	Case is >= battmax		
    	gosub gridtie            'Turns on inverter relay
    case is >=pvhigh           
        gosub AllSystems      'Turns on both relays
	Case else                  
   	gosub standby         ' < pvmin. Turns off both relays
end Select				' Resume here after case is executed

This should work

   Case is >= pvmin and is >= batt and is <= battmax

But this one seems to be better,

   Case is >= pvmin 
        if pv >= batt and pv <= battmax  then etc...

Thanks. I'll try that tonight when I get back home.

I got tripped up with this one too...
Needs to be along the lines of:

Case is >= pvmin 
        if (pv >= batt) AND (pv <= battmax)  then etc...

Good luck and happy coding.

Works great. Thanks guys.
