Adding std. deviation measure to a column

[jconte]

I have a column of data and a calculated measure for the standard deviation of that table (STDEV.P). I've been trying to create an additional column that contains the data column with the standard deviation added to each data point. Ideally, it would look something like this:

y0	std	y_plus_stdev
5e-09	1e-10	5.1e-09
2e-09	1e-10	2.1e-09
Total	1e-10

However, what I'm getting is a value for the standard deviation that somehow becomes zero when I try to put it in the column formula.

y0	std	y_plus_stdev
5e-09	0	5e-09
2e-09	0	2e-09
Total	1e-10

For some reason, this works when hardcoding a value for the measure.

I managed to figure it out. Simply adding STDEV.P() to the column formula directly instead of through a measure seemed to do the trick. Not sure why though (or why I didn't find this out earlier).
