could be a multidimensional property you have on the slider, so you would need to address it as
effect("Low number")("Slider")[0];
or
effect("Low number")("Slider")[1];
aso.

- I'm using two one dimensional sliders. One is named "Low number", the other "High number".CyBrainX

Expression in the text field source text:
A = thisComp.layer("Null 1").effect("FirstNumber")("Slide...
B = thisComp.layer("Null 1").effect("SecondNumber")("Slid...
this.value = A.value + "-" + B.value;
this works for me. Using .value.toFixed(0) also works.

uan,
That third line was the one that worked for me. I think the [this.value] part was what I was missing. I sorted it out last night by breaking it into to three text objects but it's good to know how to concatenate basic strings in the future.
Thanks.

After all that, I decided to use the version I had before with three text objects because the dash was set at one position and it looked better than when it was in one test layer moving around.

- I remember having to do that in flash some years ago as the solution:)uan
- I tried to think of this in Flash terms. String(some math expression or numerical value) would make Actionscript accept the value as a string.CyBrainX
- it as a character string.CyBrainX

I love when I search for an expression and come up with a QBN thread from three years ago. Will I ever learn?

If I remove .toFixed(0) I get the error
"Error line 3...invalid numeric result (divide by 0?)"

Ok, I finally got beyond error messages with this.
x = effect("Low number")("Slider");
y = effect("High number")("Slider");
String(x) + " - " + String(y);
but the text displayed is
[OBJECT PROPERTY] - [OBJECT PROPERTY]
