These values are then automatically inserted into their corresponding fields in the form. You are then free to enter whatever you like for α and "pooled?" to continue. oh! That is absolutely marvellous, thanks very much indeed yes, works perfectly. No need to reach for the Prime and its Import function any more thanks again, great stuff. Noted re caveats.

In my case, the samples are generally the same size, so your method works perfectly, thanks again.
