Card visual ignoring values under 0!

[forgetmenot]

Hi all, 

I hope someone can help me. I have created a measure to bring back the value of a particular month. This works for absoute values. However, when value is minus it shows it as blank. 

I want to be able to show the actual value i.e  -£10,000 etc. 

How can I acheive this? I am a beginner so would apprecaite any help.

I have used the following measure: 

Measure= CALCULATE(SUM('KPI'[Value]),

DATESINPERIOD('KPI'[Date],DATE(2023,06,01),-1,MONTH))

Hi @forgetmenot 

Can you share a sample of your file? It's difficult to understand what's happening without knowing how it is defined.
