Change a variable with a if

[CapitaineFlam88]

How to change a already defined variable with a if?
I am trying to change the variable mToday when the market is open.

I get an error and the mToday down here are hilighted.

lready assigned: mToday at 102:1

def vpmToday =  0;
if marketOpen >= 0930 and marketOpen <= 1600 {
mToday = Round ( Total / FromOpen, 0);
} else {
mToday = 0;
}

here are a couple versions to assign a value

ver 1
this method will allow you to assign more than 1 variable

def start = 930;
def end = 1600;
def daytime = if ( SecondsFromTime(start) >= 0 and Secondstilltime(end) >= 0 ) then 1 else 0;

def mToday;
def var2;
if daytime then {
   mToday = Round( volTotal / minFromOpen, 0); 
   var2 = 1;
 } else { 
   mToday = 0; 
   var2 = 2;
}

ver 2

def start = 930;
def end = 1600;
def daytime = if ( SecondsFromTime(start) >= 0 and Secondstilltime(end) >= 0 ) then 1 else 0;

def mToday = if daytime then Round( volTotal / minFromOpen, 0) else 0;
