                employeeNumber = Convert.ToInt32(txtPNumber);
                hours = Convert.ToDouble(txtHoursWork.Text);
                gross = hours * hourlyWage;
                txtGrossPay.Text = "£" + Convert.ToString(gross);
                tax = gross / 100 * 20;

                txtIncomeTax = "£" + Convert.ToString(tax);

                insurance = gross / 100 * 7;

                txtNI = "£" + Convert.ToString(insurance);
                deduction = tax + insurance;
                txtTotalDeduction = "£" + Convert.ToString(deduction);

               



            }
            else
            {
                txtName.Text = "";

You do it well in your else clause why dont you do it before: like in txtIncomeTax = "£" + Convert.ToString(tax); Here you assign a string to a textbox. This is not correct.

yes, instead of

txtIncomeTax = "£" + Convert.ToString(tax);

I put:

txtIncomeTax.Text = "£" + Convert.ToString(tax);

and it seemed to work fine...

[lonelyrider]

name = txtName.Text;
employeeNumber = Convert.ToInt32(txtPNumber);

Please pay your attention here
I beleieve txtPNumber is the name of the textBox assigned by you and not a variable if yes thats why its throwing that error

TRY THIS:
name = txtName.Text;
employeeNumber = Convert.ToInt32(txtPNumber.Text);
