Function expected error- Tab style display

please assist on how I can solve the problem

Hi Shandulo,
I would recommend you check the following:
The same version of Citect SCADA and service pack is installed on both machines (e.g. Citect SCADA v7.20 SPK5A)
Make sure you only backup/restore the custom files, and not the "system" level projects.
There is a chance that the cicode function was moved to the core product. So you need to make sure the system files (in Tab_Style_Include) are matched to the correct version of product installed.
Let me know how you go.
Kind regards
Olivier
