[AccessD] calculation

Hi Pedro 

You need as well to finish the SQL statement to include your tablename:

Select 
  Patient, 
    Dcount("*","[Test]","Patient = '" & Patient & "' AND B = 3") / 
    Dcount("*","[Test]","Patient = '" & Patient & "'") * 100 As
  Percentage_B3
From
  tblYourTable
Group  by 
  Patient;

/gustav

Hello Gustav,

yu have a great look.
Indeed there was one after the second '" & Patient &.
But i still receive a syntaxerror, operator is missing. Then    group    is 
selected.

Pedro
