Dear Stata Professionals

I am currently suffering from saving file name as local value

The code I have used is as following

Code:
levelsof listid , local(levels)
local vlname: value label listid
local vl: label `vlname' 1007
display "`vl'"

levelsof listid2 , local(levels)
local vlname2: value label listid2
local vl2: label `vlname2' 1007
display "`vl2'"

save `v12'_`v1'_1007, replace
export excel using `v12'_`v1'_1007, firstrow(varlabels) replace
when I apply the code above following outcome is shown

file __1007.xls saved

I wish to save names as

abc_def_1007.xls

Your help will be appreciated.
