Loop Condition not getting satisfied when the variable value is set through GEL script

I am trying to run a gel script from where I am setting value of a variable to be true so that the "if" loop condition in source code is satisfied.

Below is the code snippet:  (where true is a enum member with value 1)

//----------------------------------

if (valid == true)
{

if (newPosition == true)
{
 newPosition = false;
CommandActionResetFlg = true;
}

UpdateCommand();
}
else
{
 newPosition = true;
}

//-------------------------------

Though the GEL script, I want to satisfy the first if condition i.e. (valid == true);

So, I am setting valid =1; (i.e true) in the GEL script just before this condition.

While debugging its showing value of valid as true (condition satisfied), though the condition is still failing;

Pl. suggest.
