Hi,
It might be that I just have to tidy up my spreadsheet. I have a list of dates that is 90% dates and 10% text in my RegClinicDate column. If a patient books a clinic, I put a date; if they don't I put No Response; if I am still waiting, I put a dash "-".
I'm trying to count patients who we are waiting for and am using this formula:
CountIf(PatientTable,RegClinicDate="-")
But I get an error message saying Data Type: Number
Thanks in advance
