If you could post your formula we may be better able to offer a solution.

hi,

First thanks for ur reply.I have used this formula.

 if{MQM_USP_PatientQIDataElementValuesForReport;1.DataElementId}="AMI_39" then
    if{MQM_USP_PatientQIDataElementValuesForReport;1.DataElementValue}="true" then
          Chr(254)
    else
        
         Chr(168)
  

Else
 
    if{MQM_USP_PatientQIDataElementValuesForReport;1.DataElementValue}="false" then
     Chr(254)  
    else
         
       Chr(168) 

 

Please check it..I have given formula for both Yes and No options but  how to know whether it is true or false for yes..because on the basis of boolean value in Yes we can assigned the boolean for No.I saw some object name..whether it will be helpful..or not if yes then how we can use that in formula.

 Regards,

Om

Set a variable to hold the value for which I take to be CHR(168) then change the var based on the following code in the first part I removed the nested if and uses an 'AND' because both must exist to be a true, if that is incorrect change as appropriate...
---------------------------------
var = Char(168)

IF  {MQM_USP_PatientQIDataElementValuesForReport;1.DataElementId}="AMI_39" AND
  {MQM_USP_PatientQIDataElementValuesForReport;1.DataElementValue}="true" THEN
         var = Chr(254)  

ELSE
 
    IF 2{MQM_USP_PatientQIDataElementValuesForReport;1.DataElementValue}="false" THEN
     var =  Chr(254)  
 -----------------

Hope this helps

Ok, I got that, I used the following to convert yes and no to numbers

If {RA.MCData} = "Yes" then 1
Else IF {RA.MCData} = "No" then 0

Now I need to SUM the "1s" and then use that sum to get a percentage of another field or sum...
 
Can someone help?  I cannot just drop the Formula field into the Formula expert.
 
Thanks, need help ASAP!

Create your formula for the 1 and 0 in the Formula Expert - I'm going to call it MCData_1or0. 
 
Create another formula to do the sum - I'll call it MCData_Sum.  If you need the sum at a group level it will look like this:
 
Sum({@MCData_1or0}, {table.group_field})
 
If it's a total sum for the report it will look like this:
 
 
To do the percentage, create another formula that looks like this:
 
If {field or other sum formula} = 0 then
  0
else
  {@MCData_Sum}%{field or other sum formula}
 
You need to make  sure that you're not dividing by 0, hence the first part of the If.  The '%' operator does the percentage calculation (a/b*100) for you.
