I need to incrementally increase or decrease cell values until I get an exact
result in a dependant cell:- 19.9, 19.8, 19.7...19.5...bingo!
Is there a way that I can achieve this with mouse clicks...each click
subtracts/adds 0.1 - or any other integer that I specify - to the cell value?
To nitpick, 0.1 is not an integer.
Here are a bunch of options that do not require any VBA code.
If you want a cell to be an exact number, why not just enter that number
into the cell?
If you are changing one cell so as to achieve a desired result in
another cell, check out Excel's Goal Seek capability. See Tools | Goal
Seek... Or, check out it's "big brother" Solver (Tools | Solver...)
Finally, if you still want to click and change a cell value, check out
the Spinner button from the Forms toolbar. If the toolbar is not
visible use View | Toolbars > Forms. Now, click and add the Spinner
control to the worksheet. Right click the control and from the Control
tab set the appropriate values including the Cell Link field.
To achieve increments less than whole numbers (say 0.1), link the
control to an intermediate cell and in the cell where you want the
actual value, enter ={intermediate cell}/10
