How to sum of all value from a firebase bucket

[Sraban_Ahmed]

I want to show total sum of “value” from a firebase bucket not “Tag”
example
firebase project bucket name is “Bangladesh” and tags are cities and each tag has value of number of city

Bangladesh
Dhaka: 50
Comilla: 40
Chattogr: 27
Khulna :14

I want to show the total of values like 50+40+27+14= in a label

remember tag are increase day by day
