Map bubble size by selected value and nothing selected

[eeroso]

Area	Age group	Value
New York	0-30	1.1
New York	30-60	6.2
New York	60+	20.1
New York	All ages	6.1
Los Angeles	0-30	1.1
Los Angeles	30-60	4.2
Los Angeles	60+	23.6
Los Angeles	All ages	10.1

So I have similar table like that and Im supposed to show values on a map based on area. If nothing is selected in any filter, it is supposed to show "All ages" value on each bubble size and tooltip. If a age group filter is selected in other visualization, it is supposed to show corresponding age group value in bubble size/tooltip.

If I just put area as area and value as Size in map, it works for the age group filters, but if nothing is selected it shows the chosen aggregate over all age groups. Instead I want only to show "all ages" value when nothing is selected. And no, All ages is not sum,average, or anything like that over those age groups - its based on things like population and other stuff which is not provided by the data provider.

Looks like I managed to solve it by myself

IF (

SELECTEDVALUE('Table2'[Age Group]) = BLANK(),
SUM('Table1'[All ages value]),

SUM('Table1'[Value])

)

Table2 is table with same agegroups in other visual (which is the initial filtering visual on click)
"All ages value" is calculated column which only contains all ages values (all other age groups are 0)
