Reports - getting numeric value from commodity collector

Hi Derek,

Thanks. Yes I was trying that but am having problems with using denom

Using this:

 (set! mytaxes (gnc:numeric-mul num
                   (gnc:double-to-gnc-numeric tax-rate 100 GNC-DENOM-REDUCE)
                   ;(gnc:numeric-create 33 100)
                   100 GNC-DENOM-REDUCE))

Gave me a figure 100 times to large. I tried different figures for
'denom' argument but to no avail.

Best regards.
Darryl
