Thanks Chris. I think I'm still struggling with the collect() function. In the original module (year), the formula states IF X THEN if Y then Collect() ELSE 0. When I drill down to this, it takes me to a new module where the figures are being collected from.
In the new monthly module, the formula is still the same, but when I drill down, it doesn't take me to that original module? I'm left with just 0?
