Help with allowing check congruency with swedish words for the colors in stroop

Hi!

I'm using the stroop test decribed here https://www.youtube.com/watch?v=ODhDaAbj_DQ

We conduct a study in Sweden and need the instructions and stimwords to be in swedish. I have translated this, but then the script doesn't allow me to look at congruency, since all my data is incongruent when the stimcolor attribute, green for example, isn't equal to the stimword attribute "grön" in swedish. How can I change the script to check congruency from this present one:

'The following script determines if this is a congruent (the color and word match)
'or an Incongruent (the color and word do not match) trial.

'If the attribute called "StimColor" matches the attribute called "StimWord" Then
If c.GetAttrib ("StimColor") = c.GetAttrib ("StimWord") Then
'The trial is congruent
c.SetAttrib "Congruency", "Congruent"

'If the attribute called "StimColor" does not match the attribute called "StimWord" Then
ElseIf c.GetAttrib ("StimColor") <> c.GetAttrib ("StimWord") Then
'The trial is incongruent
c.SetAttrib "Congruency", "Incongruent"
End If

To another one that allows for the swedish words; green=grön, red=röd, blue=blå, yellow=gul to work as stimwords ? I have tried changing the stimcolors to swedish words, but then the program doesn't recognize them as colors at all.

I'm not used to programming/scripts (I'm a physiotherapist) Is what I ask above doable, and if so, can somebody here help me with it? 

Best regards
