It's not clear what you're deducting there... Shouldn't just UC1 be the produce of Disc1 and MSRP1, ie the price after the discount?
This is the information that the form user will fill out "Form User":
Dealer Discount (Disc1)="44%"
Unit MSRP (MSRP1)="$5599.00"
Currently the form is doing: 44%*$5599=$2464
I need to know minus the $2464 from the $5599 to get the answer for UC1
Is the Discount field set as Percentage under Format?
Yes it is
Then you can use this as the Simple Field Notation formula:
MSRP1 * (1-Disc1)
So what does the (1) stand for in (1-Disc1)?
It doesn't stand for anything. It's just the number one... The value of a percentage field is between 0 (0%) and 1 (100%). So if you want to show the result after applying the discount then you need to multiply the amount by its complementary value, ie, 1 minus the discount value.
It appears you want the expression to read:
MSSRP - (MSRP * Discount)
Which could also be written as:
(1 * MSRP) - (MSRP * Discount)
And applying the Associative Law of Multiplication becomes:
MSRP * (1 - Discount)
Compute out the discounted price both ways and the result should be the same.
