How to compute in the text box from the computed value from combobox and numericupdown

I have my basic pay that is computed from the Basic Pay (The position code with a value ex. Code: A, Rate/day: 500) multiplied by the No of days worked.

if (cmbPositionCode.SelectedItem == "A")
                txtBasic.Text = (500 * nudDays.Value).ToString();
            
            else if (cmbPositionCode.SelectedItem == "B")
                txtBasic.Text = (400 * nudDays.Value).ToString();
            
            else
                txtBasic.Text = (300 * nudDays.Value).ToString();

And now, I need to compute for the SSS Contribution that is if the basic pay is within the given range (ex. 10,000 & above, SSS Rate is 7%).

SSS Contribution = Basic Pay * SSS Rate

I tried this but I was not really sure on how to do it

            double sscontri;
            sscontri = Convert.ToDouble(txtBasic);
            
            if (txtBasic >= 10000)
                
                sscontri = txtBasic * 0.07;
                txtSSS.Text = sscontri.ToString();

I'm getting an error of Operator '>=' cannot be applied to operands of type and Operator '*' cannot be applied to operands of type

I need help on how to remove this errors. Is my txtBasic inside the if wrong? TIA!

Because you can't compare txtBasic which is a control to 10000 which is int. If you want to compare the txtBasic text, you should convert it first to an int:

int basic = int.Parse(txtBasic.Text);
if (basic >= 10000)
    sscontri = txtBasic * 0.07;
    txtSSS.Text = sscontri.ToString();
