Hello, 
Whenever I tried to run my script, the program tells me that "the expression 'list.policyBRep/next' is invalid. Expression contains an unknown element or property name"
This error is in regard to my /select=list.policyBRep.nextindex in my text elements: 

<text PolicyBRep1>
/items = PolicyBRep
/txcolor = (red)
/txbgcolor = (white)
/animation = path (5000, 1, 0%, 90%, 100%, 90%)
/select= list.policyBRep.nextindex
</text>

I don't know what is wrong with this section of my script, could someone tell me what I'm going wrong? 

This is the whole script for context:

<item PolicyARep>
/1 = "score1"
/2 = "score2"
