pj,

I did post this once, didn't seem to go anywhere, apologise if it shows
up twice.

Place brackets around the K36+0 on the last 2 formulas, won't work
correctly if a value other than 0. Missed that before, sorry about
that.

=IF(L36<=30,K36+0,0)

=(L3630)*(L36<61)*(K36+0)

=(L3660)*(L36<91)*(K36+0)
