I am importing data from an excel file, and then performing a fourier transform on it, using

Fourier[data = Import["C:\\Jan04.txt", "Table"]]

which works just fine. However, the command

ListPlot[Abs[Fourier[data = Import["C:\\Jan04.txt", "Table"]], PlotJoined -> True]]

to plot the data returns the error

ListPlot::lpn: { my data } is not a list of numbers or pairs of numbers

but the data is a list of numbers! What's going wrong here?
