Use of timeline across a number of different reports

[Rachel1980]

Hi All,

Power BI newbie here, desperately trying to get a report I created to work alongside a timeline.

i think the issue is that one report has the date (which I've used for the timeline) and the other also does, but I can't use 2 timelines. I did add in a start date, end date and week number relationship which the sheet is linked to, but it doesn't like it. Any suggestions....before I hit the wine. 
thanks 

Rachel
