explanation of expression

[capriconuser]

can anybody help to explain this

sum({<Date = {">=$(=vQBack)<=$(=vCFinal)"},EX.EType={'GE'},[EX.IType]={'PNC'}>}Balance)

+

sum({<Date = {">=$(=vQBack)<=$(=vCFinal)"},EX.EType={'TAllocated'},[EX.IType]={'PNC'}>}Balance) * sum({<[EType] = {'GE'}>}Data)

[jonathandienst]

Sum balances where

• Date between vQBack and vCFinal (probably variables)
• EX.EType = 'GE'
• EX.IType = 'PNC'

And Add to

     Sum balances where

• Date between vQBack and vCFinal (probably variables)
• EX.EType = 'TAllocated'
• EX.IType = 'PNC'

     Multiplied by Sum of [Data] where

•    EType  = 'GE'
