TypeError: u is undefined

I have been building macros for my RQ game.  I have a sequence of characteristic macros that I would like to nest to save screen space.  An example of a characteristic roll is (for intelligence) &{template:default} {{name= @{selected|name} tests Intelligence}} [[ [[@{selected|INT}*?{multiplier|5}]] [[@{selected|INT}*?{multiplier}/5]] [[floor(@{selected|INT}*?{multiplier}/20)]] ]] {{Intelligence= test value is $[[0]] }} {{Roll=[[1d100]] }} {{Special= $[[1]] or less}} {{Critical= $[[2]] or less}} It took me some time to work out how to make this work by copying stuff from elsewhere plus a bit of trial and error. I then tried to nest macros. ?{Which characteristic?|INT,#IntelligenceM |STR,#StrengthM  } I stuck to two characteristics INT and STR and made additional macros for those, after a substantial further amount of trial and error, and I think I have made the necessary substitutions in the code.  I have seen lots of error messages where the mistakes were obviously mine and I have gone in, again and again tweaking codes. I thought I had it and then I got this message: TypeError: u is undefined This is not covered in your help forums and potentially takes me even further out of my depth than I already was. Any suggestions welcome but please do remember that I do not speak code! :-) Stephen

Since you have the initial macro working, I would say simply don't use a query for which attribute you want to test.&nbsp; Use a chat menu instead, since that can totally avoid all that html replacement business. <a href="https://wiki.roll20.net/Chat_Menu" rel="nofollow">https://wiki.roll20.net/Chat_Menu</a>

My kind of thinking!&nbsp; If you cannot see a way through, go around.&nbsp; :-)&nbsp; I will have to do more reading, I have never seen, never mind used a chat menu... Thanks for the pointer.

When I first started using Roll20, I used queries everywhere.&nbsp; Then I decided I didn't like answering queries every time I did something.&nbsp; Then I discovered chat menus and barely remember how to do queries anymore...

Well, I succeeded.&nbsp; Will be playing with that for some time. If anyone knows why the original error occurs, that would be interesting but the chat menu is a solution that achieves the desired end result. Thanks Kraynic.

I have encountered a problem with the chat menus.&nbsp; I have a macro which works as a standalone but not when invoked via a button.&nbsp; It seems to work but then nothing appears in chat.&nbsp; I am presuming there is something to do with selected characters but cannot work it out. The macro in question is as below.&nbsp; Happy for any input... &amp;{template:default} {{Action=@{selected|token_name} engages @{target|token_name} }} {{Roll=[[1d100]]}} {{Success=[[floor(50+((?{@{selected|token_name}|STR,(@{selected|curSTR})|CON,(@{selected|curCON})|SIZ,(@{selected|curSIZ})|INT,(@{selected|curINT})|POW,(@{selected|curPOW})|DEX,(@{selected|curDEX})|CHR,(@{selected|curCHR})})-(?{@{target|token_name}|STR,(@{target|curSTR})|CON,(@{target|curCON})|SIZ,(@{target|curSIZ})|INT,(@{target|curINT})|POW,(@{target|curPOW})|DEX,(@{target|curDEX})|CHR,(@{target|curCHR})}))*5)]] }} Essentially it allows one character to test a characteristic against someone else's...
