I am trying to validate two date fields on a custom expense report prior to allowing someone to sign the document digitally.

"WeekEnding" Date/Time Field

"Signature" Signature Field

"Date" Date/Time Field

I am inputting this into both the initialize and calculate fields for the Signature object:

If(WeekEnding.rawValue != null && Date.rawValue != null){

    this.access="open";

}else{

    this.access="readOnly";

}
