## Why didn't my field expression produce the expected result?

I'm new to Qlik Sense and don't understand the syntax well.

I change a data measure expression because it didn't produce accurate results.  But, I don't know why the first expression didn't work.  Can someone explain why?

// Removed the following two line as they produced incorrect results.

//[QUEUE_DATA.DURATION]={'<3'},

//[QUEUE_DATA.DURATION]={'>0'},

// ... Replaced the prior two expressions with the following one.

[QUEUE_DATA.DURATION]={1,2},

Try this

[QUEUE_DATA.DURATION]={">0<3"}

Thank you.  That worked.

I'd still like to understand what the original syntax means such that it didn't produce the desired result.

Within set analysis a single field can be used only once... when you used this

[QUEUE_DATA.DURATION]={'<3'}, [QUEUE_DATA.DURATION]={'>0'},

only green part was recognized and red was ignored... you can do this like this

{<[QUEUE_DATA.DURATION]={'<3'}>+<[QUEUE_DATA.DURATION]={'>0'}>}

Breaking it down into two different sets union-ed together

Does this make sense?
