Data validation and populating cells

[Flashman101]

Good morning,

I am trying to populate cells on a timetable document based on selections in two cells with data validation options and date/lengh and date/duration of project

Can any one help? Trying and failing with conditional formatting

Provide some example data.

You cant attach files on this forum. There are tools on this forum for adding small spreadsheet images
