fernando check it up you, if i do the instr() -1 separately works... dou
you see the code before answer:

    strinchar = Mid(strinchar, 1, InStr(strinchar, ")", -1) - 1) ' does not
work

IDE said error invalid argument, but if i do:

    psotionlen = InStr(strinchar, ")", -1) - 1   ' separate the stolen and..
     strinchar = Mid(strinchar, 1, psotionlen)  ' put in here then works
?!?!?!!?

works, why?
