hi.
I have little problemo. I have data like this in excel :

Time Level (dB)
0.05 77.66
0.1 75.68
0.15 77.82
0.2 76.93
0.25 76.93
0.3 78.15
0.35 79.14
0.4 74.36
0.45 77.7
0.5 78.86
0.55 79.35
0.6 77.87
0.65 78.69
0.7 79.26
0.75 81
0.8 79.98
0.85 81.56
0.9 79.42
0.95 77.99
1 78.1
Let's say the average of the Level is X.
I want to locate the value which nearly equall, maximal 1.0 above or
1.0 below the (X-5). Can somebody help me write some excel macro for
it?
