Here's the simplest way. This calculates the sum of the fourth column

```
Dim TotalSum As Double = 0
Dim TempNode As ListViewItem
For Each TempNode In ListView1.Items
TotalSum += CDbl(TempNode.SubItems.Item(3).Text)
Next
MsgBox(TotalSum) ' Debug
```

and it assumes that each item is a valid number.

A bit safer solutions uses TryParse to check validity:

```
Dim TotalSum As Double = 0
Dim TempNode As ListViewItem
Dim TempDbl As Double
For Each TempNode In ListView1.Items
If Double.TryParse(TempNode.SubItems.Item(3).Text, TempDbl) Then
TotalSum += TempDbl
End If
Next
MsgBox(TotalSum)
```

and again calculates the sum of the fourth column.

What if, "I would like to create a query statement that would give me the sum of the column(total_bill)?"

like this:

("Select SUM(total_bill)FROM tbl_estimates WHERE estimation_date = '"& Textbox1.Text & "'",2)

I would like to Displat it in my listview.

My, Query statement is absolutely right, but then there is still an error that doesnt have a suggestion.

Maybe you guys could help me..... :)
