Single Value Slicer

Hi All,

I've searched far and wide for the ability to add a single value slicer to my report. The good news is I found one, I was able to retrieve a copy of a report showing exactly what I was looking for. The report I saw posted at PowerPivotPro showed a single value slicer that utilized the function "Generateseries=(start,end,interval)" upon attempting to add this to my report I was not able to achieve the same results. I noticed an icon I have not seen, it was a table with a question mark. I have a table containing a container count and am attempting to use a slicer to influence other items within the page. I would like it to be a single value entry either slider, or enterable field so users can update to the exact amount of containers. Unfortunately, unlike the report I am attempting to sample, was only able to have either a vertical slicer with tiles, or a ranged slicer.

If anyone is able to assist I would appreciate it.
