CGG and links with parameter

Hello,

I'm trying to make some reports with CGG.

="http://localhost:8080/pentaho/content/cgg/Draw?script=/01_dashboard_set/Reports/mydashboardwithparam_Graph2.js&outputType=png&userid=joe&password=password&paramparamPeriod=" & [paramPeriod] & "&paramparamType=" & [paramType]

My problem is, that paramType has 2 words, e.g. "Type Normal", "Type Special". That means, my link is not working. Is there a chance to get links working with parameter that have 2+ words without replacing " " with "_"?

Thanks for your help.
