I am having trouble using a custom token attribute to validate the answer to a question.
token attribute_3 is the age of the participant at the time on interview. (eg. 55) When we ask a participant how old they were when they last had an operation, I want to use this age(attribute_3) to validate their answer.
eg. If the age of their last operation is greater than token attribute_3, throw up an error.
This is what I have tried up to date, without any luck.
Validation Equation:
((782874X662X3938SQ001 >= 0) and
(782874X662X3938SQ001 <= [attribute_3]) or
is_empty(782874X662X3938SQ001)) and
Validation Tip:
{if(((782874X662X3938SQ001 >= 0) and (782874X662X3938SQ001 <= [attribute_3])), '','Please enter an age that is less than you current age.’)}
I thought maybe the token attribute is a text field and needed to be converted. If so how do i do this?
((782874X662X3938SQ001 >=0) and
(782874X662X3938SQ001 <= TOKEN:ATTRIBUTE_3) or
is_empty(782874X662X3938SQ001))
