Ok your suggestion has worked. I was able to get 40. Pressing Control then shift then enter was something I did not knew.
Now I am trying to clear the colors of excel of column F from All taxi sheet. So that I can post here and explain the problem.
I had put my cursor on topmost of column F there became a downward arrow sign and when I selected clear formatting I got a popup
saying that we can't do that to a merged cell.
So I started manually deleting the formatting of column F. I reached F1132 hold down shift key and down arrow key
row number 1136 is having merged cells so this makes the work difficult as I can not select the entire column now.
So is there a solution for this situation so that I can clear the formatting of entire column.
