Count instances of values in a query

[theaybaras]

Hi all,

I have a table [tblClientLog] and a subtable [tblCAssessments].

CAssessments is a combobox that looks up a table called [tblAssessList]

AssessList has 2 columns, an autonumber PK and a string for the title of the Assessment. When the user meets with a client, they input the valid demographic details and time spent with client, and then in the subtable CAssessments they input any assessments they ran with their client. I need to have a report of the total number of hours spent between Date 1 and Date 2. Also, I need to have a report on the number of times each assessment in [tblAssessList] exists in [subtblCAssessme nts].

I am not sure where to begin to have this do what I need it to do. The other thing is that I need it to count each instance of a unique assessment, but if someone adds an assessment title to the list, I need a count for that one too. I really don't know where to begin! Any suggestions? the metadata for the three tables is as follows
[code]
Table Name=tblClientL og

Field; Type; IndexInfo
C_Key; AutoNumber; PK
C_Location; Numeric; (looks up tblLocations)
C_Client; String
C_ClientDate; Date/Time
C_StartTime; Date/Time
C_Hours; Numeric
C_CType; Numeric; (looks up tblcontacttype)
C_Interaction; Numeric; (looks up tblinteracts)
C_Gender; Numeric; (looks up tblgenders)
C_Age; Numeric
C_Race; Numeric; (looks up tblethnicity)
C_Orient; Numeric; (looks up tblorientation)
C_PhysOrth_Disability; Yes/No
c_Blind_Disability; Yes/No
C_Deaf_Disability; Yes/No
C_Cognitive_Disability; Yes/No
C_Developmental_Disability; Yes/No
C_MentalIllness_Disability; Yes/No
 

the subform to the previous table is as follows

CA_Key; autonumer; PK
CA_C_Key; numeric; FK from tblClientLog
CA_Ass; numeric; (looks up tblAssessList)

the list of assessments is in tblAssessList is as follows

ASS_Key; autonumber; PK
ASS_Name; string; (title of assessment)

An example of what I need is as follows. The data in my tblAssessList is:
01; Addiction Severity Index
02; Beck Depression Inventory
03; Outcome Questionnaire 45.2

tblClientLog (filtered to a few pertinent fields)

C_Key; 01
C_Client; A1B37C
C_Hours; 3
C_ClientDate; 05/19/2007

C_Key; 02
C_Client; A2B37D
C_Hours;1
C_ClientDate; 04/08/2007

tblCAssessments
CA_Key; 01
CA_C_Key;01
CA_Ass; Addiction Severity Index

CA_Key; 02
CA_C_Key; 01
CA_Ass; Outcome Questionnaire 45.2

CA_Key; 03
CA_C_Key; 02
CA_Ass; Outcome Questionnaire 45.2

CA_Key; 04
CA_C_Key; 02
CA_Ass; Beck Depression Inventory

I need to have something that counts these instances and reports:
Addiction Severity Index = 1
Outcome Questionnaire 45.2 = 2
Beck Depression Inventory = 1

Total Client hours from date 1 to date 2 = ?
(i.e. hours between 04/25/07 and 05/25/07 = 3)
(i.e. hours between 03/25/07 and 05/25/07 = 4)


If that wasn't as clear as I'm hoping, please let me know! I'd appreciate any guidance you can share!

Thanks so much!

Ok in reverse order. The issue of counting against unique assessment - use a crosstab query. If you try and build a report directly licked to the crosstab it will not pick up on newer assessment types added so build a report on the fly for now.

building a query based on the client will give to the consultations between 2 dates ( use the criteria to request date input) then a calculation in the same query to sum the hours taken

Hi there!

Thanks so much for your response. I've got my crosstab query, and it's doing exactly what I was hoping for! What I'm not sure of is what you are talking about for my report. How do I create my report 'on the fly?' Also, for the second part, when I make my report and query for client hours between two dates, how do I get it to pop up a form for the user to enter the dates into?

Thanks so much! Already you've been so much help!
