Suppress field in header

Question

I feel like there should be a simple solution for this but I am having the hardest time figuring it out.  I am using crystal report 9 and there is a group header that contains the account number and beginning balance.  I want to show the account number at the beginning of each page if the transactions exceed one page, however I only want to show the beginning balance on the first page of the transaction list by account.  I want to somehow suppress the field showing the begining balance until a new account number is reached.  Here is an example of the layout of the report:
--PageHeader
Account                                                  Balance
--GroupHeader1
1191-0041                                               1,000.00
--Detail
xx    xxxx     xxxx                xxxx    xxxxx
xx    xxxx     xxxx                xxxx    xxxxx
xx    xxxx     xxxx                xxxx    xxxxx
xx    xxxx     xxxx                xxxx    xxxxx
                                                              end of page 1
page 2
--GroupHeader1
1191-0041
--Detail
xx    xxxx     xxxx                xxxx    xxxxx
xx    xxxx     xxxx                xxxx    xxxxx
xx    xxxx     xxxx                xxxx    xxxxx
xx    xxxx     xxxx                xxxx    xxxxx
--GroupFooter
                                                             ending balance
                                                              end of page 2
page3
--groupheader1
1193-0001                                                2,000.00
--Detail
xx    xxxx     xxxx                xxxx    xxxxx
xx    xxxx     xxxx                xxxx    xxxxx
xx    xxxx     xxxx                xxxx    xxxxx
xx    xxxx     xxxx                xxxx    xxxxx
I hope this makes sense, but this is how I want it to be laid out noticing that on page 2 the account number is the same as page one therefore the balance is suppressed but when you get to page 3 there is a new account so the balance is shown. 
I'm used to designing reports in Access where there is an onchange event of the header, is there anything like that in crystal reports?  Does anyone have suggestions on how to accomplish what I want to accomplish?
Thank you in advance!

Jamie,
How you do this will depend on whether or not there is a one to one relation between the account and the beginning balance or a one to many relation.
If it is one to one then you can conditionally suppress the beginning balance with a form similar to;
= previous()
If there is a one to many relation (the balance displayed on page 2 differs from that on page 1 for the same account) then you will need to set up a counter formula in the Group Header;
WhilePrintingRecords;
Numbervar X:= X + 1
and reset the counter in the Group Footer;
WhilePrintingRecords;
Numbervar X:= 0
You could then conditionally suppress the beginning balance when X is greater than 1.
Numbervar X;
X > 1
