Using generated reference to a variable

With @Diksha's help, I have generated a correct-looking reference to a variable using the following formula:

concat('variables(','''','strHTMLChartSect',string(variables('intSectNum')),'''',')')

When I try to use the outputs as an inputs to access the value of the variable, it adds the text for the variable, but not the value of the variable:

My Question

How do I get Flow to return the value of the variable and not just the text reference to the variable?

Thank you for your assistance with this; it is much appreciated.

@Hardesh15 was helping me with something similar earlier, and got close, but we never quite got to a solution.

If it helps, here is the Peek Code:

Hi @BenDonahue

Looks like the issue is on your concat expression. What you trying to produce in your concact expression?

Re: Using generated reference to a variable

@abm,
I believe I have what I want:
variables('strHTMLChartSect1')

How do I use this string to access the variable, strHTMLChartSect1?

Re: Using generated reference to a variable

I think what I should have done was generate the variable name on it's own:
concat('strHTMLChartSec",variables('SectNum'))
, and then insert that output in the next compose:
variables(outputs)
I'll try that and see if it works.
