counting yes in yes/no data types
Do not us Count but Sum like this --
=Abs(Sum([SOP])) =Abs(Sum([Protocols])) A 'Yes' is stored as a -1 (minus one) and the Abs function removes the negative sign. -- Build a little, test a little. "Emelda" wrote: I am having trouble getting a total count in the report footer for yes/no data types. For example, if I have a document number as the primary key in one table containing general information and as the foreign key in a second table containing document type information and other information. The different types of documents are listed as checkboxes (yes/no data type) and there can be more than one document type selected for each document number. Then in the report footer, I am trying to get a total count of the individual document types (e.g., SOPs and protocols). I am using =Count([SOP]) and =Count([Protocols]) with the associated label. Instead of obtaining a total number of documents for which the checkbox for SOPs is checked and the total number of documents for which the checkbox for protocols is checked, it returns a "yes" for both. How can I get Access to count the documents whose SOP checkbox is checked and return a number value and make sure it does not include those with a null value? I figure that there is an easy solution to this, but I seem to be missing it. Another question is regarding the use of checkboxes compared to using combo boxes. Are there advantages or disadvantages? It seems that with combo boxes only one choice can be selected whereas multiple checkboxes can be used. Thank you in advance. |
