Dear all,
i am a beginner programmer about VBA mainly for Excel Applications.
Please i need your help about a problem that feels me sick.
I try to create the following macro:
1. Open an excel file (and it's ok)
2. Load a sheet (and it's ok)
3. apply the sumif (it doesn't work with the file loades at point 1 but it works fine with the main sheet)
NOTE: the variables lv_stringa_appogio is a String and lv_counter_hours is Double
The error occurs when i call sumif is Error 13 (i have tried to use only WorksheetFunction.Sumif... but the result is an other error).
i hope in a your help and reply.
Best regards.
