Hi  
I am using invoke code to loop around a datatable and update a specific column value from “Subject to revie” to “Subject to review”  
I get syntax error at line 2. What could be the issue? I’m using VB . I pass the dt\_Req as In/Out argument and it is a Datatable

For Each row As DataRow In dt\_Req.Rows  
If row(“Status”).ToString().Trim().ToLower() = “subject to revie” Then  
row(“Status”) = “Subject to Review”  
End If  
Next

Hi @besakkiappan46

You should make sure that you set the argument as DataTable in the invoke code activity. You should not get any errors. If you still get errors, you should try closing UiPath Studio and reopening it.

 ![The image shows the "Invoked code arguments" section for a program, displaying a DataTable argument named "dt_Req" with an input/output direction. (Captioned by AI)](https://global.discourse-cdn.com/uipath/original/4X/7/d/e/7de01104d94d20a69969d3d57330f1da99ef0efc.png)

@besakkiappan46,

Make sure your code is following these points:

1. **Capitalization and Punctuation** : Ensure every statement ends with a proper punctuation mark, including the main statement block indicators.
2. **Quotes and Case Sensitivity** : Verify that the string comparisons are accurate in terms of quotes and casing.

Try this code:

```auto
For Each row As DataRow In dt_Req.Rows
    If row("Status").ToString().Trim().ToLower() = "subject to revie" Then
        row("Status") = "Subject to Review"
    End If
Next

```
