Rating visual

[Sofinobi]

Hi all,

please, i have a dax measure to show a star rating (not exactely stars), but it doesn't work, it shows me an error "mdxscript(model) (346, 30) calculation error in measure"
the measure is :  

Rating Visual =

VAR _Full = INT( DIVIDE(AVERAGE(COM_ThirdParty[Rating Column]),10) )

VAR _Empty = 10 - _Full

RETURN

REPT(UNICHAR(9899), _Full) & REPT(UNICHAR(9898), _Empty)

* the error comes from the rating column, cause when i change for another column, it shows me a result correctely.
the Rating Column is calculated :  

Rating Column = DIVIDE([Sales],[Solde Max],0)*100

the result with another column is like this image:
