WEB UX initialization

Hello. I want to run the WinCC OnlineTrendControl in
WEB UX initialization using a VBS script:

objCon2.TrendAdd = "Trend"&CSTr(i)
objCon2.TrendColor = colors(iC)
objCon2.TrendTagName = Mid(paramNames(i),16,30)
objCon2.ValueAxisAdd = "Value Axis"&CSTr(i)
objCon2.ValueAxisTrendWindow = "TW1"
objCon2.TrendTrendWindow = "TW1"
objCon2.TrendTimeAxis = "TA1"

objCon2.TrendValueAxis = i
objCon2.ValueAxisInTrendColor = 1
objCon2.TrendPointStyle = 0
objCon2.ValueAxisAutoRange = 0
objCon2.ValueAxisBeginValue = CInt(Mid(paramNames(i),1,3))

objCon2.ValueAxisEndValue = CInt(Mid(paramNames(i),5,3))

objCon2.ValueAxisLabel = Trim(Mid(paramNames(i), 9,6))

But nothing works in Web UX! What am I doing wrong?

Are there detailed instructions?

Thanks​
