Iterate global variable and question

#1

1) Give a description of the problem
Iterate global variable

2) What is the expected behavior?
@globalvariable = @globalvariable (-/+) 1

3) What is happening/not happening?
Don’t know how to do this.

I am trying to iterate a global variable. I want to know how many people are present at my house at a given time, and iterate the global variable up or down as people enter/exit. First of all, I don’t know how to put custom lines of code into wC. I am new to this whole thing. And two, I don’t know how to code it so as to iterate the global variable.

Any help is appreciated.

Make sure the global variable is defined as an integer. Then when someone changes to present you can set the variable with either a value {@yourGlobalVariable} + 1 or as an expression @yourGlobablVariable + 1 Then just do the opposite when someone leaves.

When using the value field you need the {} brackets around any variable, function or expression.

When using the expression field you don’t need the {} brackets but you will need single or double quotes around any string text you want.

How do I do the @globalvariable + 1? I can get it to where it says…

Do x2 Set variable {@globalvariable} = {@globalvariable}

But how can I change it to variable + 1… I don’t see anywhere I can manually change anything, only the prepopulated stuff.

Or if I change it to Value, it just lets me change the integer, I can’t input anything.

#4

Nevermind. I think I found it!

Changed to expression, and ended with this…

do x2 Set variable {@globalvariable} = {{@globalvariable} + 1};

Is this correct?

#5

You have the do part right. However, instead of setting the variable avian, like you have it. You need to manually type in {@globalvariable} + 1

I believe that will do it?

I don’t use a lot of counters

You don’t need the curly brackets in the expression field. You can copy and paste exactly like I have it in my original response

Passing multiple variables in the same expression
