I'm trying to use #ADD, and cant figure out why its not working (as I've used this with variables many times before).

So for this example we will have variables AA, BB, CC, DD

First of all, when I'm using the #ADD function if AA was already equal to 6 and I wanted to add 1 to now equal 7... #ADD AA 1 but instead of the output being 7 I get an output of 61, then if I add 1 more to it the output then becomes 611.. etc etc.

Next, I've tried to add the variables AA, BB, CC to equal DD.
I've tried %eval(AA+BB+CC) that didn't work. Then I tried to nest it with %eval(%eval(AA+BB)+CC)) and that didnt work. Then I tried #VAR EE AA+BB and then DD=CC+EE. Its not working at all. What it does is squishes all the numbers together as explained in the #ADD example (IE: AA=1 BB=2 CC=3 then output of and of the equations to mean AA+BB+CC= 123 as opposed to the correct answer of 6)

Also, if this matters at all - I'm trying to put these variables in the status bar. The variables themselves are working just not when I try to add/subtract/total.
Using CMUD v3.33

If you get the output "61" then CMUD thinks that your AA variable is a literal string value instead of a number. In CMUD, "adding" for strings is the same as concating.

You shouldn't need %eval in CMUD.

What you need to do it look at how the variables are getting set. If you do:

AA = "6"

then that sets it as a string variable. If you do:

AA = 6

then that sets it as a numeric variable. To *force* a string to become a number, use the %int function.

In CMUD, use normal expressions and assignment rather than using the old zMUD #ADD and #MATH commands. For example, this works fine:

Okay changed all the variables from "auto type" to "integer" and that worked. Thanks much!

Still had to use %eval for the status bar, but I was unable to use it as a totaling variable but just as the equation. Using just the parenthesis just returned the output (value of AA + value of BB + value of CC)

Is there a way that I can set the value of a variable to an equation? I want the value of DD to ALWAY be equal to AA+BB+CC. I tried changing DD back to an auto type variable and putting the equation in the value field but I failed again.
