Error in variable testing condition

There's an error in the variable testing condition. Variable values can't be generated until it's fixed.

Automatically regenerate variables?

No variables have been defined in this question.

xxxxxxxxxx
 
random(0..1)+random(0..99)/100

JME function reference

This variable was automatically created because there's a reference to it somewhere in this question.

Error

Warning

This variable is an interactive HTML node. Interactive HTML nodes can not be relied upon to work correctly when resuming a session - for example, attached event callbacks will be lost, and mathematical notation will likely also break.

If this causes problems, try to create HTML nodes where you use them in content areas, instead of storing them in variables.

Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?
