Just saw the rest of your problem.
replace sizebmp5=10+`i' if bm<bm4 & sizep5==`i' & timeyear==`t'
Might solve your problem.
HTH,

With `i' I want the variable signalling the corresponding sizep5 portfolio. Because this variable changes from 1 to 5, I need the term `i'; I also tried 1_`i' but it did not work.
