Why might "eachpick" be valid for a debug statement but not for a string operation?

Code:

var skills as string

foreach pick in gizmo from Skill

  skills &= "!" & eachpick.idString & " & "

  debug "Add to " & eachpick.idstring

  nexteach

This is code I have within an eval statement. If I comment out the first statement, it works and prints the idstrings. If I don't comment out the first statement, it gives me an error message of "Reference to undeclared variable: 'eachpick'".

What's the difference?

You mis-capitalized idstring.

"Reference to undeclared variable" is the compiler's last resort - it means "I really can't figure out what you're trying to do - perhaps you meant to declare a variable earlier, and you're trying to use it here?"

Thank you. That is helpful. Not directly in my attempt to have the Advances not allow duplicate Skills, but it is helpful in getting me a it further,

Ah! And I figured out the Advances. I was able to repurpose the eval on AdvBoost to have the already-picked choices not show up. I know someone else had had this issue a while back... they probably already found their own solution. :)

Code:

<eval value="1" phase="Final" priority="1001">

  <![CDATA[

    var skills as string

    

    foreach pick in gizmo from Skill

      skills &= " & !Skill." & eachpick.idstring

      nexteach

    field[advDynamic].text &= skills

    ]]>

  </eval>
