Hi Paul, sorry for not making it very clear.
combx_SelHVField was showing all column headers. I have now changed it to show only those column headers which has numeric values.
In the above case, if the field selected is either SubAmt or TAT, then the samples should be the highest 20 values from the filed selected in each Category.
Hope it is clear now.
Maybe by ranking the values for each stratum and then sort and mark Yes for first 20 in each stratum
Thanks in advance!
