Cant call a variable in a Chart

[Tian-Jay]

Hello, ive set up a variable as per Using the Variable Extension in Qlik Sense | VizMind. However everytime i try to call this variable in a chart i just get Invalid Dimension. my variable is called vDimension, i have set this up in the Qliksense Dashboard bundle - Variable Input, and have given it two Values, which are two columns from my data (however i get invalid Dimension regardless of the data contained). Im calling to the variable on the chart in the Field section using $(vDimension) and i just get errors, can anybody help?

i have followed the guide step for step

There is no definition of the variable, if you want a variable to work as a dimension in UI, it must be aggregated over some other dimension, otherwise it is can be used as a measure only and thus using it as a dimension generates that error.

okay thank you! Could you direct me to any resources for how to do that? or alternatively send the code for doing this?
