How to use if else statement with other indicator fucntions

[mutualguru]

I have a code like this

mrsi=RSIa(C,14);
ma1=MA(C,200);
if((mrsi >70) AND C>ma1 )
var=1;
else
var=0;

if ( var == 1 ) 
{             
Do some stuff
}
else
{
}

The problem is when i execute this i am getting this error

Error 6. Condition in IF, WHILE, FOR statements has to be Numeric or Boolean type. You can not use array here, please use [] (array subscript operator) to access array elements

Any idea how to solve this error

mrsi and ma1 are array cannot use If...else statement.

mrsi=RSIa(C,14);
ma1=MA(C,200);

//--Method 1
var = mrsi >70 AND C>ma1;

//==Method 2
var = iif( mrsi >70 AND C>ma1, 1, 0);

If...else can only use in single element such as Boolean or Numeric Number.
such as in a looping:

mrsi=RSIa(C,14);
ma1=MA(C,200);

var=null;
  for(i=0; i<Barcount; i++)
  {
      if (mRSI[i]>70 && c[i]>ma1[i])
          var[i]=1;
      else 
          var[i]=0;
  }

OR

Example of input from Param...() possible of using if...else

     me = Paramlist("Select w", "mutual|guru|mutualguru|");

    if (me == "mutual")
   {
      Title = "Mutual Friend";

   }
   else if (me == "guru")
   {
       Title = "Amibroker Guru";

   }
   else
    {
 
       Title = "Mutual Friend and Amibroker Guru";
    }

Thank you for the quick reply I have changed my previous code to your 2nd method

mrsi=RSIa(C,14);
ma1=MA(C,200);
var = iif( mrsi >70 AND C>ma1, 1, 0);  

if ( var == 1 ) 
{             
Do some stuff
}
else
{
}

Here also the same error at if ( var == 1 ) . I cant use IIF here because its a multiline code

You simply do not understand the difference between an array and elements of an array/numeric values.
