grade + siz might need conversion depending on their type. Report would then be based on myCursor.

Close . . . very close. I apologize - the report has fields that reference MEMVAR ACBUNDLE2, ACBUNDLE4, ACBUNDLE6, ACBUNDLE7......."

In psuedocode . . .

data1.bundle(conditions:data1.grade=gdValue and data1.siz=szValue and data1.length=2)

is added to

data2.bundle(conditions:data2.grade=gdValue and data2.siz=szValue and data2.length=2)

is added to

data3.bundle(conditions:data3.grade=gdValue and data3.siz=szValue and data3.length=2)

is added to ...

saved as a variable to be referenced by the report

this is done EXACTLY
