Subscript out of range error

I have a data report that is not connected to a datasource, etc. until runtime. On this report I am using text fields which I try to bind at run time. I keep getting a "Run time error '9': Subscript out of range" error on the lines referencing the text fields. I have verified my section number and spelling. Any ideas on what is causing this error? Here is my code:

Set drServCostAcctRpt.DataSource = DE
drServCostAcctRpt.DataMember = "ServiceCostAnalysis"
'set fields on report
drServCostAcctRpt.Sections(1).Controls.Item("txtService").DataField = "Service"
drServCostAcctRpt.Sections(1).Controls.Item("txtService").DataMember = "ServiceCostAnalysis"
drServCostAcctRpt.Sections(1).Controls.Item("txtWCost").DataField = "TotalCost"
drServCostAcctRpt.Sections(1).Controls.Item("txtWCost").DataMember = "ServiceCostAnalysis"

Thanks in advance!

thats pretty much telling u that section(1) doesnt exist i guess. i think i have found section numbers to be all over the place, so try zero, or 2 or 3 even, or loop through the sections in the collection, and find out the numbers that are available.

Thanks! That was it. Even though the report said section1 it had an index of 3.
