Script syntax in faceplate library

Hello

i use TIA Portal V18 with an WINCC RT Advanced

I create an object in my library and i would like to set the digit number with external parameter

So i prepare the script, 

Select Case SmartTags("Properties\NB_Digit")
Case 0
"T_Value".FormatPattern="999"
Case 1
"T_Value".FormatPattern="999.9"
Case 2
"T_Value".FormatPattern="999.99"
Case 3
"T_Value".FormatPattern="999.999"
Case 4
"T_Value".FormatPattern="999.9999"
Case Else
End Case

 Where "T_Value" is my numeric item (I/O field)

Could you tell me what mistake l've done?

regards

I continue to investigate

I use the debugger, the error is at the line "Set Number= GetObject("T_Value")"

 The output from debug is :

'HmiRTm.exe' (Script): Loaded 'Script Code (WinCC Runtime Advanced)'.
Unhandled exception at line 48, column 1 in Script.vbs
0x800401e4 - unknown exception

Sub NbDigit_Value_Sensor_1_Vue_1_14815241256573_11997185255746()
Dim Number
Set Number= GetObject("T_Value")
SmartTags("Test1_Value_Sensor_1_Vue_1_15011848256589_11997185255746")=1
Select Case SmartTags("digit")

Case 0
Number.FormatPattern="999"
SmartTags("Test1_Value_Sensor_1_Vue_1_15011848256589_11997185255746")=2
Case 1
Number.FormatPattern="999.9"
SmartTags("Test1_Value_Sensor_1_Vue_1_15011848256589_11997185255746")=3
Case 2
Number.FormatPattern="999.99"
Case 3
Number.FormatPattern="999.999"
Case 4
Number.FormatPattern="999.9999"
Case Else
End Select

End Sub

 I hope with those informations it will be eaier to get an answer
