Incrementing Total not correct(adding +1) in some group totals

Question

Hi All,
I have an incrementing total that appears to work fine except when I try to display the total's final count only SOME groups have a +1 count. There doesn't seem to be a logical reason for it.
Any ideas?
Incrementing total formula:
Whileprintingrecords;
if Not({Command.BI_UPD_DT_TM} > {@f_ConvertRevYrMo_DtTm})
then
Global numbervar memberlinecnt := memberlinecnt +1
else
memberlinecnt+0;
Formula to call incrementing total's final group total:
Global numbervar memberlinecnt:={@f_RRTMemberIncrement};
memberlinecnt;
Note: I've not been able to use Running Total fields with this report because I need to evaluate totals based on group criteria and there are multiple groups and criteria.

Answer 1

Hi Sharon,
I do have a reset, just didn't include it in my post.
Reset
//@Reset (Place this in the group header section suppressed)
WhilePrintingRecords;
Global NumberVar memberlinecnt:= 0;
Like I said,the whole thing appears to work, counting for ever group, resetting; except for only some groups, the total is +1 of the total. I don't know why.
Thanks,
John
