Query Assistance - Calculating percentage

Question

Greetings,
I may just be looking at this for way to long and not seeing the proper coding/syntax
required to accomplish what it is I am trying.
I have one query to figure out an overall count for each organization in a database. I
then have a second query to figure out the success rate count to compare to the
overall count per organization. I am running the second query inside the <cfoutput>
of the first query to achieve the desired count/display intended.
The overall and the success counts are displaying as I intend them to. However, I
am unable to get the percentage part to work. Perhaps someone can look at my
code and layout to see where it is I am failing. I have provided the desired look and
my code below for review.
I am certainly open to suggestions on how to do it differently / better, should someone
have an insight on how to accomplish my desired outcome.
CF = CF8
DB = MySQL
Thanks in advance

Answer 1

Try replacing this line
<cfset percent = ((#rs_attempts.recordcount# - #rs_1_attempts.recordcount#)*100)>
with
<cfset percent = #(rs_attempts.recordcount - rs_1_attempts.recordcount)*100#>
Not sure on the brackets though - if not try
<cfset percentWorking= #rs_attempts.recordcount - rs_1_attempts.recordcount#>
<cfset percent = #working * 100#>
