I have been using goal seek successfully to back into a known number. This works great with a handful of lines - now I need it for 100s (probably 1000s) of lines. Any help would be greatly appreciated.
Col A = constant (known)
Col B = variable (unknown)
Col C = 1.5*Col B (unknown)
Col D = variable*2080 (unknown)
Col E = (Col C*Col A) (unknown)
Col F = Col D+Col E (Where I have been using the goal seek and manually entering Col G # into goal seek) - would like it to pull Col G's number
Col G = Known Number (i.e., what should be in Col F).
Can anyone help me automate?
