count non-zero items occuring between 2 known dates

[Ron-]

Hi, this is my first post, so please excuse me if my question isn't as clear as could be.

For each of my staff I need to count if they worked 15 or more days in the 30 days preceding a statutory holiday. (As a follow on problem... If they have worked 15+ shifts then I'll need to calculate the sum of their hours over the 30 days / 30) .

I tried the functions below but they didn't work. (the Name1 column records the number of hours worked that day's shift) The actual count in my test case is 5.

=COUNTIFS([stat],"=STAT",[Date],"<[@Date]",[Date],">=[@Date]-30",[Name1],">0") result: "0"
=COUNTIFS([@stat],"=STAT",[Date],"<[@Date]",[Date],">=[@Date]-30",[Name1],">0") result: #VALUE!
=IF([@stat]="STAT",COUNTIFS([Date],"<[@Date]",[Date],">=[@Date]-30",[Name1],">0"),"NO") result: "0"


Thanks for the help!

Though I must admit to being a little bemused by the Table format formula. Just not the structure of the comparison.
