I am using PieChart from recharts. I want to display my data as a percentile. I try to convert the data sting but then the data start doesn't work. How can I do it?

const data01 = [
        { name: "Dönen Varlıklar", value: asset_1 },
        { name: "Duran Varlıklar", value: asset_3 },
      ];
var asset_1 = (assets.titles[0].values[0].value)*100
var asset_3 = (assets.titles[1].values[0].value)*100
...

<PieChart width={500} height={300}>
    <Pie
        data={data01}
        cx={250}
        cy={130}
        innerRadius={60}
        outerRadius={80}
        fill="#8884d8"
        paddingAngle={5}
        cornerRadius={20}
        dataKey="value"                                                                                            
   > 
        data01.map((entry, index) => (
        <Cell key={`cell-${index}`} fill={COLORS[index % COLORS.length]} />
   </Pie>
   <Legend/>
   <Tooltip />
