How do I evaluate variables properly?
I tried $eval(%messagetxt,3)
but then all the commas doesn't show up which means I cannot set the background. Help?

/help $eval $eval(text,N)
Evaluates the contents of text N times. If N isn't specified, the default is N = 1. If N is zero, text is not evaluated.
This allows you to recursively evaluate identifiers and variables in a line of text. Basically, if you don't want to evaluate a variable, you do $eval(%var,0). If you want to evaluate a variable normally (one time), you do $eval(%var,1). If you want to evaluate a variable 5 times, you do $eval(%var,5). $eval( %Variable_Name, Number of times you want to evaluate it)

What are you talking about? The normal way to evaluate variables is... by just their name: fex //echo -a %messagetxt
I'm sure you have something else in mind, so can you paste an example of what you're trying to do?
/.timerQ 1 0 echo /.timerQ 1 0 $timer(Q).com

I have %messagetxt set to:
2,15Mp3 System: Duration $duration($calc($mp3(%mp3).length / 1000))
So I will have to evaluate them if not it will show:
2,15Mp3 System: Duration $duration($calc($mp3(%mp3).length / 1000))
But when it evaluates, it shows:
15Mp3 System: Duration 3 mins 7 sec
See the 15?

I just pasted that line into mIRC and it displayed perfectly, blue text, gray background, no 15.

How are you trying to display %messagetxt and where? Is it a channel/query window with /echo? Or? An example of the actual command you're using would be helpful.
/.timerQ 1 0 echo /.timerQ 1 0 $timer(Q).com

Try this
/set %messagetxt $+(2,$chr(44),15Mp3 System:) Duration $duration($calc($mp3(%mp3).length / 1000))
//echo -a $eval(%messagetxt,2)
Edit- added the missing parenthesis.

Wow, I think we've just found another undocumented identifier!  > /set %messagetxt $+(2,$chr(44),15Mp3 System:) Duration $duration($calc($mp3(%mp3).length / 1000)
> //echo -a $eval(%messagetxt,2)
* Invalid format: $evalnextLooks like $evalnext() is acting exactly like $eval(), but yet it's evaluating the text one more time (ie. N+1). For example, //echo $eval($!me,1) >> $me
//echo $evalnext($!me,1) >> Online

Eh, that's come because I missed a parenthesis when I copied from trenzterra's post : :tongue:
Someone, (qwerty maybe) posted about $evalnext on the old boards.

Your solution seems to solve the problem anyway  and no wonder it was qwerty
