percentage formula in crystal report 8.5

I am doing one project using vb6.0+access+crystal report8.5

some error occur during the crystal report.

Query Name

seqquery:

SELECT segment_trans.division_name, sum(segment_trans.Total_value) AS total, 
       division_master.Target
FROM segment_trans, division_master
GROUP BY segment_trans.division_name, division_master.Target;

crystal report percentage formula:

{(seqquery.total * 100) / seqquery.Target }

Error: This field name is not 开发者_JAVA技巧known.

note: Total_value and Target field's datatype "Text"

how to solve this ?

Try changing this:

sum(segment_trans.Total_value) AS total, 

To this:

sum(segment_trans.Total_value) total,
