Re: Table Formula: Update column, then update value

[torys.anderson@gmail.com (Tory S. Anderson)]

When I apply the formula 
  #+TBLFM: $4=$3*$2::$hrs=vsum(@I..II)::$ttl=vsum(@I..II)
It doesn't give me any errors, but it also doesn't do anything to $4. So if I change one of my hour amounts, the "hrs" field will update appropriately, but not the "cost" field, which remains unchanged. It appears that the initial formula is not doing anything.
