Hi, HGB_VAL should be realted with data to apply filters, ie:

SET vHGB=5;

Data:
LOAD * Inline [
HGB_VAL, Unique_Blood_Unit
8.7,2
4,1
];

"count( {<HGB_VAL={">=$(vHGB)"}>} Unique_Blood_Unit" returns 1
"sum( {<HGB_VAL={">=$(vHGB)"}>} Unique_Blood_Unit" returns 2

it is realted to data

HGB_VAL is left-aligned, it means it's beign oinnterpreted as a string not a number,

Try converting it while loading:
LOAD
Num#(HGB_VAL,'.',',') as HGB_VAL,
...

Naveen,

It is working in my case, just check your expression
vHGB= 5;

=count( {<HGB_VAL={">=$(vHGB)"}>} Unique_Blood_Unit)

To make it work HGB_VAL should be a number, to convert a string to a number you can use Num#(), the exact sentence needed may vary based on your local settings for numbers, try different parameters for Num#():

You can try until this expression returns a number: Max(Num#(HGB_VAL,'.',','))+1
