What I actually wanted was for it happen automatically, so that the page will scroll with the time changing, so that it will alway be up to date.
Is it possible to say link it to the conditional format of the cell, and as the colour of the cell changes, then the page scrolls????, just an idea.
First, just to be accurate, the CFs (conditional formatting) don't change the cell's color when the time changes, they change the cell's color when A2 updates. A2 doesn't update if someone just scrolls around the sheet without changing anything. You can verify this by letting the computer sit idle until the next 15 minute segment, then just scroll around the sheet changing selection, but don't change any cell. You will see that A2 doesn't update and the CFs don't change the cell's color. Be sure and scroll the screen so that the correct column is not up against the frozen pane. Then change any cell, and you will see A2 update, the CF change the cell's color, and the screen will scroll to the correct column.
Obviously this difference is moot as long as the user is actually typing.
I can improve the macro so that A2, the CFs, and the scrolling all update when the user changes selection (they won't have to change anything). It just needs one line of code added to Scroll_Col. Find this section of code and add one line
But if you want the screen to scroll even if no one is sitting at the computer, it can be put on a timer. I don't like timers because they can be confusing to people and they can be unpredictable on slow or overloaded computers. Also, if your computer goes to sleep to save energy, the timers quit running also. Obviously if the computer goes to sleep no one would know that the timer quit, but as soon as someone sits down at the computer, all the timers that went dormant execute, and that can cause trouble. I don't think that your timer would cause trouble, but since I don't use them much I can't guarantee that it won't.
I think that adding that one line into Scroll_Col will satisfy you. If you want it put it on a timer, I can set it up for you.
There's just one situation (that I can think of) that you probably have.
When the user is at the beginning of a 15 minute segment (and the screen has been scrolled to the correct column) and is moving around the screen and then wants to have the screen scroll back to the correct column, how can they do it? They don't want to wait 15 minutes to have the screen automatically scroll back, they want to be able to trigger it themselves. That's the decision you need to decide. How do you want to allow the users to trigger the scrolling themselves? A button on the screen, a menu item, a right mouse click item, a double click on a column heading, or what?
