Currently working on a laboratory calculation worksheet for measuring moisture weight increases at work, but stumbling on the final average calculations. I want to calculate the average of the first occurrence of a number in adjacent columns from a range.The other entries, which occur in no particular order, are a mixture of numbers and text (eg. N/A below).(* are the required values I need calculated)...

C1 C2
N/A N/A
N/A N/A
N/A 20*
40* 15
35 10
30 7

Average = 30

I want everything to appear in the range for observation and future comparisons, but only want the average of the first numerical occurences - (40,20) above. I suspect one approach is a mixture of the IF(Logical test, True, False) and ISNumber and ISText fuctions all nested together which I tried but got really confused...Even trying Excel's rather comprehensive help menu. Note: The above numbers and text are actually formula results based on the IF(Logical Test, True, False) where True returns the number, and False the N/A text from other cells.
Help here in the provision of a formula(s) or a another approach would be great...

Cheers...

If your input data isnt changing, then just use the average formula, and manually select the cells you want to reference.
