Is there a way to get a summary for a variable?

I am creating a report that I use summaries to get totals for various groups. I was unable to summarize a formula (error read "field cannot be summarized" I am assuming b/c it contains summaries)
So I created a variable which I thought would help me get around that problem, however I still cant summarize it.

Any suggestions?

Thanks

I am making an income statement in which I take the current months GL totals and break them down by GL account type (revenue, expense, etc) I also am required to show percent of revenue for each gl account and a percentage of revenue total for each gl account type.
So I have 2 groups,
GL account type,
Gl account number

I use formulas to get the totals for the GL account types by putting them in the detail section, suppressing that sections and then summarizing them by group.

everything works fine expect that I cant get the summary for the percentage of revenue (b/c I want to sum a field that already uses summation)

SO I created a variable:

Global NumberVar TotalRevenue;

TotalRevenue:=If {GLIncomeStatementStage1.GLAccountType}= "Net Sales" then
Sum ({@Current Period Credit}, {GLIncomeStatementStage1.GLAccountType})-Sum ({@Current Period Debit}, {GLIncomeStatementStage1.GLAccountType})


then I created a variable for GL account total

Global NumberVar TotalGLAccount;
TotalGLAccount:=


If {GLIncomeStatementStage1.GLAccountType}= "Net Sales" then
Sum ({@Current Period Credit}, {GLIncomeStatementStage1.GLAccountNumber})-Sum ({@Current Period Debit}, {GLIncomeStatementStage1.GLAccountNumber})
else Sum ({@Current Period Debit}, {GLIncomeStatementStage1.GLAccountNumber})- Sum ({@Current Period Credit}, {GLIncomeStatementStage1.GLAccountNumber})

then I created a variable to do the math for each GL account percentage of revenue:

WhilePrintingRecords;
Global NumberVar TotalRevenue;
Global NumberVar TotalGLAccount;
Global NumberVar PercentageRevenue;

PercentageRevenue:= if TotalRevenue = 0 then 0 else ( TotalGLAccount/TotalRevenue)*100


Now I need a total for that variable, PercentageRevenue in the report footer, GL account type

I hope this help, sorry it is so long. Maybe I am thinking about this from the wrong angle???
