I'm using a "Calculated Value" form control with a lookup function along with the parseLookup function to pull information from a Vendor list. Sometimes the Vendor list does not have values in all the fields (ie: "Contact Name" or "Fax" may be empty) which results in #Value! on my form.
I have unsuccessfully tried IsNullorEmpty(ControlName) rules to hide any blank answers.
Examples of my lookup function:
lookup("PReq XTbl Vendor", "Name - Biz Partner No", parseLookup(Vendor), "Contact Name")
How can I either hide the #Value! on my form when there is no returned value from the lookup function
How can I only run the lookup when there is a value to return
Either of the above should be viable solutions in my scenario.
