Using a variable in set analysis

[#1]

I cannot get the following expression, using set analysis, to work.  It is a chart expression that needs to show Reserves >= an amount contianed in the variable vReserve.

Sum ({$<[Current Claim Reserve] = {$('>=vReserve')}>} [Accident Counter])

[#2 · Accepted solution]

the expression is

Sum ({$<[Current Claim Reserve] = {">=$(vReserve)"}>} [Accident Counter])

sorry.
