Put variable in another variable

I have this variable defined:

'Número da coluna ID Cliente
Public Const NrColIdBDC As String = 1

In a module i came to the end with:

PrimeiraColunaSearch = NrColIdBDC

Although since i went to this with a .find function, excel thinks NrColIdBDC is a text, how can i make it look for NrColIdBDC.variable

Is there such a function i can put:
PrimeiraColunaSearch = look variable number for PrimeiraColunaSearch

Hope someone can help me, i'm stuck :/
