I'm having trouble graphing data on a worksheet that has variable ranges.
Can anyone spot the problem with this code? The problem is always with
setting a range for the data.

Here are my variables - I know they work just fine.

xaxis = "A" & "51" & ":" & "A" & 51 + xrange - 1
projected = "D" & "51" & ":" & "D" & 51 + xrange - 1
actual = "E" & "51" & ":" & "E" & 51 + xrange - 1

And here is the first bit of the code for the graph.

Charts.Add
ActiveChart.ChartType = xlXYScatterLines
ActiveChart.SeriesCollection(1).XValues = "Sheets(sheetname).Range(xaxis)"
ActiveChart.SeriesCollection(1).Values =
"Sheets(sheetname).Range(projected)"
ActiveChart.SeriesCollection(2).XValues = "Sheets(sheetname).Range(xaxis)"
ActiveChart.SeriesCollection(2).Values = "Sheets(sheetname).Range(actual)"

"sheetname" is the name of each individual worksheet in the file. That
variable is a string that I've populated earlier in the code.

Thanks!
