You have to use the LOCAL keyword.  From the MPASM help file:

len   equ 10           ; global version
size  equ 20           ; note that a local variable
                       ; may now be created and modified
test  macro size
      local len, label ; local len and label
len   set size         ; modify local len
label res len          ; reserve buffer
len   set len-20
endm                   ; end macro
