Code:

new string[60],new level = PlayerInfo[playerid][pDetSkill], new levels;
if(level >= 0 && level <= 50 ) levels = 1; // this will show that players detective level is 1 
format(string,sizeof(string),"Detective Level: %d - (%d  more times to level up)\nLawyer Level:%d - (%d more times to level up)",levels,51 - level);
ShowPlayerDialog(playerid,303,DIALOG_STYLE_MSGBOX,"Jobs Level",string,"Close","");

i've done this only for Detective to show you a way to make it in dialog but make other by yourself and you will understand how it is done, i havent tested the code but it should work.
