Heatmap not working

[JoshFraser]

Hi, 

I am looking for some guidance regarding heatmap on Power BI desktop. 

On my dataset I have latitude and longitude (all to 5 decimal places) and UK postcodes for our stores and am looking to compare this to the number of sales for each store to give us a map of which geographical locations are strong in sales and which are weak. 

My problem arises when I come to use the heatmap graphic as when I put in the longitude and latitude or postcode nothing displays. I have tried formatting the data as decimal numbers and text with no success on either occasion.  

I have checked the global settings and maps are enabled so from what I can see this should be working but isn't. 

Any tips or guidance would be massive appreciated. 

Thanks
