linking worksheets (linking cell B4 in worksheet1 to worksheet 5 and so on)

Hi,
I'm not a expert on excel but hope someone can make this problem easier for me.

I have 10 customers, each named under a separate worksheet, therefore i have 10 worksheets.plus 1 sheet for summary of all the sheets.
Each customers worksheet has got 5 columns and 5 rows.Date in column A so 4 weeks will have 4 rows of dates under column A. column B is headed as previous balance. column c is headed as bill for this week.column D is headed as total balance.column E is amount paid this week.
In the summary sheet i have got customers names in column A and the rest of the columns are week dates. so if the summary is of the last 2 months then i will have 8 columns dated from example sep06 to nov06.

I want to link the bills for each customer to the summary worksheet so i can calculate the total sales for 2 months. i have already tried to do this by copying a bill from a customer and paste link to summary worksheet. but by doing this i have to individually copy each cell and paste link it to the summary worksheet.
is there an easier way to do what i am trying to do?
i've tried to give as much information as i can so you can read and look to see what i am doing.

please could anyone sort this out.
