Help with VBA code to calculate changes made in Column

Hello all you geniuses. I have another VBA issue. I have built a sheet, and what I'm looking for is when anyone changes the date in column J (Last Update), it counts that as updated in cell F3 (Actions updated since last review). I have the VBA code as:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Sheets("Sheet1").Range("J10:J136"), Target) Is Nothing Then
Range("F3").Value = Range("F3").Value + 1
End If
End Sub

However, what I'm realizing now is I need F3 to reset to 0 every time the worksheet is opened, so that it's only counting the current updates and doesn't continue to increase the count of total updates made.

Thanks in Advance

Thanks Trevor. This certainly worked. Now a sub question as it relates to this setup; If I expand the workbook to, lets say 20 sheets, all identical but for different offices, this will reset f3 to 0 on all of them correct? If I wanted it to be sheet specific but not apply to the workbook as a whole, is there a way to accomplish that?

Thanks for the help. I've uploaded a new file with 3 sheets in the workbook, when I use the code now nothing updates. Maybe I'm missing something, but I went through the lines in the code, and everything seems right.

Yes, it does seem to be working, thanks John. I erased all the code and re-entered it. It is working as described now. However, I'd also like a different option, maybe this needs a new post. What about having a sheet update the count in F3 only when a date is changed in column J. So basically if there is a 2 in F3, and someone changes a date in column J, then it would reset to a 1. If 3 dates are changed in column J then F3 would show a 3. Does that make sense?

What I am trying to accomplish is; lets say there is a "3" in F3 on Sheet1. Now if someone goes in and views sheet1 but doesn't make in any changes, it stays as a 3. However, if somechanges 1 of the dates in column J, then F3 would show a 1. If someone changes 4 dates in column J, then f3 would show a 4. So basically it wouldn't reset to 0 ever.

I'm only looking for F3 to change by how many dates are changed in column J. So, if there are 6 line-items and someone only changes dates for 2 of them, then F3 would show a 2. If someone changes 5 of the line-item dates then a 5 would show in F3. It'll always vary depending on who is going in and how many items they update at that time.

Yes it'll be a shared workbook. The people that will be updating it and the people that will be looking at it will be different. Basically, higher ups will view the sheets to see how things are progressing (and who isn't), managers will need to go in and update as needed. I could always have the managers update F3 manually with how many they updated, I was just trying to avoid that step if possible. So having the change log creates an extra step that the higher ups want to avoid.
