I am trying to creat a formula in excel and cant figure it out. I have 6 colums, they are as follows:

```
Column 1:Name
Column 2: task performed
Column 3: date performed
Column 4: report number
Column 5: date due
Column 6: status
```

I would like Column 6 to show "overdue" in red when column 2 is blank. I am trying to make up a formula that will change column 6 to "completed" in green when ANYTHING is written column 2. Can anyone help me make this formula?
