adding data from two colunms
I hope you can help me with this.
I have two columns one estimated cost the other actual cost
est cost actual
100 50
300
400
500
t 1300 total $$$
I would like the total under the actual colunm to use the est cost value if
the actual cost is not there, so that i have a running total of what i have
estimated and what has been already aquired.
thank you in advance
