[RESOLVED] SUM of Textboxes

Code:

---

       
Dim result As Integer
Dim rc As Integer = CType(FormView1.FindControl("rental_chargeTextBox"), TextBox).Text
Dim ssm1 As Integer = CType(FormView1.FindControl("SSMTextBox"), TextBox).Text
Dim ssm2 As Integer = CType(FormView1.FindControl("SSM2TextBox"), TextBox).Text
Dim ssm3 As Integer = CType(FormView1.FindControl("SSM3TextBox"), TextBox).Text
result = Int(rc) + Int(ssm1) + Int(ssm2) + Int(ssm3)
CType(FormView1.FindControl("total_rental_chargeTextBox"), TextBox).Text = result

---

What i am trying to achieve is if:
rc=10
ssm1=1
ssm2=0
ssm3=1
result would equal 12.
What i am getting is 1011.

Can anyone tell me why it is adding them together into a string instead of adding the textbox values together as a sum total?

Try changing this line:

Code:

---

result = Int(rc) + Int(ssm1) + Int(ssm2) + Int(ssm3)

---

To this:

Code:

---

result = CInt(rc) + CInt(ssm1) + CInt(ssm2) + CInt(ssm3)

PS Turn Option Strict on! :) (it will help you avoid problems like this)

I would also suggest turning Option Strict On, as

Code:

---

Dim rc As Integer = CType(FormView1.FindControl("rental_chargeTextBox"), TextBox).Text

---

is technically not a valid line.
