G'day, You have aliased RP08_R2_RETRO_PAY_SUM as r2 and referenced it as rp2 in the equation. The statement seems to be truncated too so I'm not able to determine if you've done the same with the rp1 reference. Might I also suggest you associate a name with the result of the equation as well. HTH. Cheers.
