Gauge chart showing a diferent value

[amandatf]

Hi all... 

I'm trying to build a gauge chart with the target value equal to the number of days times 10.

The measure is working fine (as checked in the bar chart --> target house is 200), but the value is not right when the same measure is used as the target field of the gauge chart, it changes to 120 (please, see the image below).

Can somebody help me? 

Thanks, 

Amanda
