Error in expression

[ckoltam]

Good morning,

Can someone explain to me why this expression is not working? I have a 2020 QlikSense version

I created a variable with the expression:

ONLY({<LAB_DESCRIPTION = {'$(=V_PRIMER_LABORATORIO)'}>} $(=DIMENSIONS_LEVEL_FIELD))

If I replace $(=DIMENSIONS_LEVEL_FIELD) with just DIMENSIONS_LEVEL_FIELD, the expression works, but the original version is what I need.

Thank you all.

Hi!

Try with double quotes:

ONLY({<LAB_DESCRIPTION = {"$(=V_PRIMER_LABORATORIO)"}>} $(=DIMENSIONS_LEVEL_FIELD))

[vinieme12]

the variable must return the field name as a string

example

DIMENSIONS_LEVEL_FIELD   =   if(SomeCondition, 'FieldA', 'FieldB')

then in expression use $(DIMENSIONS_LEVEL_FIELD)
