Description Eike Rathke 2013-08-12 21:04:44 UTC

New spreadsheet
A1: =SQRT(B1)
Do not enter any value in B1

Tools->GoalSeek
Formula cell: $A$1
Target value: 2
Variable cell: $B$1

OK => not successful, closest value 0

Expected: successful, value 4

Comment 1 Eike Rathke 2013-08-12 21:52:43 UTC

Detail: current implementation needs an existing value cell as variable cell that can be changed and the change broadcasted to recalculate the dependent formula cell(s). Probably that value cell needs to be temporarily added to the document if it doesn't exist. Needs to be checked though if doing so would interfere with ChangeTracking or cell protection or have other unwanted side effects.

On testing the duplicate, I noticed that it succeeds in 3.5.0, but maybe this is not news to you.
