I have this script, that works, to pull the new cost everytime it changes and the old price, as well as the change. However, my client wants me to do this in an expression, not a script. How can I do this in an expression. Here is my script, so you can see what I am doing:
if(HHSCSAR <> Previous(HHSCSAR), HHSCSAR, 0) as [New Cost],
if(HHSCSAR <> Previous(HHSCSAR), Previous(HHSCSAR), 0) as [Old Cost],
if(HHSCSAR <> Previous(HHSCSAR), HHSCSAR - Previous(HHSCSAR), 0) as [Cost Change],
of course the [Cost Change] is just the subtraction of the other 2 fields, I am just showing it for completeness.
