+xHi,
Probably a studpid question, but get the following error for the code below: return (“< 5”) Unmatched quote.
For both keyRemindersMagnitudeLeft & keyRemindersMagnitudeRight
Does anyone know what I need to change?
Thank you!
<expressions>
/ keyRemindersParityLeft = {
if (parameters.responseKeyEven == parameters.responseKeyLeft){
return ("EVEN");
} else {
return ("ODD");
}
}
/ keyRemindersMagnitudeLeft = {
if (parameters.responseKeySmaller == parameters.responseKeyLeft){
return ("< 5");
} else {
return ("> 5");
}
}
</expressions>
<expressions>
/ keyRemindersParityRight = {
if (parameters.responseKeyEven == parameters.responseKeyRight){
return ("EVEN");
} else {
return ("ODD");
}
}
/ keyRemindersMagnitudeRight = {
if (parameters.responseKeySmaller == parameters.responseKeyRight){
return ("< 5");
} else {
return ("> 5");
}
}
</expressions>
Since the semicolon ; is the statement separator / terminator in expressions, the ; in < and > throws off the expression parser. It thinks the expression ends at < and > respecively, and there is no matching quote.
The trick to get this to work is to use another level of indirection by definiing the HTML entities you want to insert as variables.
