The software thinks I have two variables ?

Hello everyone,
I'm trying to define an interpolation function of one variable in a Solid Mechanics model by importing data from a .txt file. But, when I click on the Plot button to display the curve, I have the following error :
"Interpolation grid axis values must be sorted in ascending order in each dimension"
I only have on dimension (ie the function has one argument) and my table contains two columns, the first for the argument, and the second for the function values, so I don't understand this error. What is weirder is that when i import another tabulated file, I don't get any error message.
Kind regards.

And the argument column is in ascending order?

Hi,
did you manage to solve this issue?
If so, I would be interest in your solution, as I got the same error message and no idea is wrong about my function definition file.
Thanks a lot and best regards,
Juergen
P.S.: In my case the problem was in the input file. There was one ambiguity which I overlooked first.
