Creating a Dynamic Graph Using Text Cell References

Good morning,

I am looking to create a graph based on a range between two cells.

The user defines the row of these cells, and then indicates the desired start and end range (ie. start column and end column) in a specific area.

Using this information, I have produced using the ADDRESS function two text cell references, which are located on sheet "References".

Results:

'Suburban (By District)'!$K$2 (Located in K4)
'Suburban (By District)'!$U$2 (Located in L4)

The sheet, row, and column are variable and determined by the user, so these locations will change depending on the user input. I want the graph to actively reflect these changes.

In any case, my assumption was that I could make the range = 'References'!$K$4:'References'!$L$4'. This does not work. I imagine I should use the INDIRECT function, but that returns the values of the aforementioned locations, not the locations themselves.

How do I create this range based on the text in K4 and L4?

Thanks for any help.

Regards,

DJW
