Hi,

I have a simple problem but for some reason i'm drawing a blank on how to solve it haha. I basically created a fit model for some data and had it output the formula into a column. Now I want to set Y and all the factors except one to values and solve for the unknown. In the example below, I want to solve for :RH assuming I have column data for all the other Variables. I can do algebra by hand and probably use the desirability manuallly..but neither seem ideal for automating the process. Any suggestions? Thanks in advance.

Example

```
(-10) + Match( :RD, 1, -0.2, 6, 0.2, . ) + Match( :O,
4, -0.2,
5, -2,
6, 0.5,
7, 0.1,
10, -0.7,
11, 0.6,
12, -0.7,
.
) + Match( :L, 1, -0.6, 2, 3, . ) + Match( :R,
"B", 0.1,
"T", -0.1,
.
) + 6 * :RH + (:RH - 15) * Match( :RD, 1, -0.5, 6, 0.5, . )
```
