Populate another cell from previous cell with multiple selections

[Spikenaylor]

Hi there.

my spreadsheet uses a code that picks from a dropdownlist and allows multiple selections into the cell and allows to remove selections from the cell. code is shown below.

It all works as it should, but now I want:

to be able to chose a selection from the dropdown list and with a particular match, it (runs another sub to do other things, in this case to populate another cell)

I want the matched selection to run the sub from an empty cell, or from multiple selection, but NOT on removing the multiple selection.

ie.

Word to match in example below is "build"

Blank Cell scenario.

pick dropdown list choose "build"

sub is called and runs.

Already polulated Cell Scenario ( cell populated with "drain, plug")

pick dropdown list choose "build"

"build" is added to cell contents by existing code, and sub is called and runs.

Already polulated Cell Scenario ( cell populated with "drain, plug, build")

pick dropdown list choose "build"

"build" is removed from cell contents by existing code, but sub is NOT called.

I am struggling to work out how to do this
any help or advice would be great

I think this would work. See red font area.
