How to pass an argument to evaluateJavaScript function?

Qt Code:

Switch view

for (int i = 0; i < centerPointsList.size (); i++)
    {
        QVariant         holdInformation = map->page ()->mainFrame ()->evaluateJavaScript (QString ("constructFileName (%1).arg (centerPointsList[0].toFloat())"));
        QList <QVariant> allListObj      = holdInformation.toList ();
        QList <QVariant> fileNamesList   = allListObj[0].toList ();
 
        std :: cout << fileNamesList[0].toFloat() << "================= \n";
 
    }

for (int i = 0; i < centerPointsList.size (); i++)
    {
        QVariant         holdInformation = map->page ()->mainFrame ()->evaluateJavaScript (QString ("constructFileName (%1).arg (centerPointsList[0].toFloat())"));
        QList <QVariant> allListObj      = holdInformation.toList ();
        QList <QVariant> fileNamesList   = allListObj[0].toList ();

        std :: cout << fileNamesList[0].toFloat() << "================= \n";

    }

To copy to clipboard, switch view to plain text mode

This results in:

"SyntaxError: Parse error on line:1 Source:undefined"
Segmentation fault

I am guessing that the error is in the way I am passing the list item to the function evaluateJavaScript.
