SubField issue in Set Analysis

[manideep78]

Dear Community

I am facing a problem in set analysis for below expression.

=Count({<DepositionCavityP={"=$(=SubField(vDepositionSelection,'|',1)&','&=SubField(vDepositionSelection,'|',-1))"}>} LensKey)

Actualli i am having a input box which consists of "4 | 12"

Now I am trying to get the expression like:  Count({<DepositionCavityP={4,12}>} LensKey).

Please help me to get this.

Thanks in advance.
