you will need to retarget your dagger and also before starting macro double click your mortar and select which poison you need to train and leave the menu for alch open (you can raise alch with this too but would be quicker if you got high alch)
it works simply by finding the poison applying it to the dagger... if you poison yourself it casts purge (did have it as bandies but not everone has it high enough to cure poison) if not it skips that part and goes on to make last on alch gump (hence why you make one and leave open).
as you gain and go on to needing the next poison up stop macro ... you'll have an alch gump up ... pick next one and replay macro.....
works for me you could use kegs instead but meh i have none lol ... you can probably make one on easyuo that destroys this but i like razor lol, use it dont use it, its all good just sharing knowledge probably more suited to someone who doesnt use easyuo... or like me cant get the thing to run lol
have fun
to install in case you dont know find the macro folder for razor... can be found in program files-razor-macros
if running vista or win 7/8 its under users-(username)-AppData-Roaming-Razor-Macros its a hidden folder so either change your settings or type it in
then create a txt file (notepad) and copy that script in to it and asve in the folder open restart of razor it will be under macros (i had problems with this as it didnt read notepad files on this pc but did on my old laptop work round was simply copy a macro you already made then open that in notepad and replace script)
