Sub OnRButtonDown(Byval Item, Byval Flags, Byval x, Byval y) Dim PrefissoTag Const NomePopup = "Misure_AI_Alm" Dim f_dir_path Dim filepath Dim ReadLineTextFile Dim objTag Set objTag=HMIRuntime.Tags ("Path") itemName = "PIT200501" PrefissoTag = "AI7_" & itemName & "." filepath = HMIRuntime.Tags("Path").read & PrefissoTag & "PAI" Call ReadTXTfile(filepath,ReadLineTextFile) Call Segnali_AI (PrefissoTag,NomePopup,ReadLineTextFile) End Sub Same script is not working with WINCC V8.0 + update 6 Error shown in GSC diagnostics is "variable is undefined : itemName". After declaring "Dim itemName" inside script, error is eliminiated. I have more than 50 nos. of PDLs and each PDL has more than 20 such objects. Now please answer the following question. 1. In WINCC 7.4 : without declaring variable "itemName" script is running fine, is there any way in WINCC 8.0 to restore same funcationality. (i had already tired "convert project data") 2. if there is no way to get old functionality - is there any way i can modified all object from all PDLs by fetching mouse event for all object. Regards,

If you know which object have this script and the names are similar, you can write an VBA Macro, which open the pictures and add "Dim ItemName" to the needed Scripts. BR, Fess.
