Form results for sliders include first item in range and then the selected item

I gave your plugin a try and when I get the emailed results, the slider shows two results when only one was selected. On a slider with a range of 1-5, step 1, if I select any number from 1 to 5, the saved data shows a 1 and then the number selected, separated by a comma.

Say I choose 3 — the results that will be saved show 1,3. If I choose 4, the slider returns 1,4. I can sort of handle that, but I know my client will be confused.

Is there a way to get the slider to return only the selected number and not the first and selected number?

Thanks!
