declaration of 'result' hides global variable

[SAM TEST]

Hi, I have this kind of "error", someone can tell me why they are telling me

does the "result" declaration hide the global variable?

double getTrailingStop( int per, datetime openTime, bool isLong, string sym = "" ) {

if ( sym == "" ) { sym = Symbol(); }
// this function will return the trailing stop of the symbol
// dir = TRUE for longs; FALSE for shorts
double result;
int startBar = getOpenBar( openTime, per );
if ( isLong ) { 
result = iHigh( sym, per, startBar ) - getStopDist( per, startBar, sym );
} else {
result = iLow( sym, per, startBar ) + getStopDist( per, startBar, sym );
}
for ( int i = startBar; i > 0; i -= 1 ) {
if ( isLong ) {
// for LONG orders
// loop through the bars since opentime
result = MathMax( iHigh( sym, per, i ) - getStopDist( per, i, sym ), result );
} else {
// for SHORT orders
result = MathMin( iLow( sym, per, i ) + getStopDist( per, i, sym ), result );
}
}
return(result);
}

That is what the warning says. Use global variables sparingly.
