variable is assigned but never used

Hi..what's wrong with this code? I declared the variable pret, and then used it, but i'm informed that is assigned but never used.

when form load{

double pret;// it's assigned but never used

if (cnp.StartsWith("1") || cnp.StartsWith("2"))

{

string an = "19" + cnp.Substring(1, 2);

string luna = cnp.Substring(3, 2);

string zi = cnp.Substring(5, 2);

string data_nastere = luna + "/" + zi + "/" + an;

DateTime data = Convert.ToDateTime(data_nastere);

TimeSpan zile = DateTime.Today.Subtract(data);

varsta = Convert.ToInt32(zile) / 356;

if (varsta <= 23)

{

if (double.Parse(tb2.Text) <= 1200)

pret = 340;

else if (double.Parse(tb2.Text) >= 1201 && double.Parse(tb2.Text) <= 1600)

pret = 486;

else if (double.Parse(tb2.Text) >= 1601 && double.Parse(tb2.Text) <= 2000)

pret = 535;

else if (double.Parse(tb2.Text) >= 2001 && double.Parse(tb2.Text) <= 2400)

pret = 583;

else if (double.Parse(tb2.Text) >= 2401 && double.Parse(tb2.Text) <= 3000)

pret = 729;

else if (double.Parse(tb2.Text) <= 3001)

pret = 1458;

}
}

Since the variable pret is assigned in a conditional statement the compiler would not know and the value is assigned only at runtime, to avoid this you can assign a default value to your variable:

double pret=0;
