Thanks Hui!
Well it accepts the name for the range now but I'm still having difficulty graphing the range.
I created a name for the range in column A using the same method, as the chart is a graph of A against E and both ranges must be dynamic.
I called the range for column A, Timestream and used =OFFSET('Formated Data'!$A$5,,,COUNT('Formated Data'!$A:$A))
for the refers to box
Following what Narayan said above, I clicked on the data series on the chart, the series formula appears in the formula bar as
=SERIES("Accept",'Formated Data'!$A$5:$A$26,'Formated Data'!$E$5:$E$26,1)
I changed this to
=SERIES("Accept",timestream,acceptstream,1)
This gave another error.
