. What training resources are available to help me learn BUSY?

The "Runtime Error 91: Object variable not set" occurs in BUSY when you attempt to use an object variable that hasn't been assigned a valid reference to an object. In other words, the variable is "Nothing" or uninitialized, and you are trying to access a property or method of that object, which leads to the error.
If error message show Runtime Error ‘91’, Object variable not set. While opening a company follow the below steps:
Step 1:We need to monitor the occurrence of the event and share the relevant data to identify the underlying issue.
Step 2: Explore an alternative approach to prevent the event from occurring, while ensuring the sharing of relevant data to pinpoint the root cause of the issue.
Step 3: Perform a thorough inspection of the data by accessing the 'Check Junk Character' feature within BUSY Software, accessible through Open Company → Housekeeping → Check Junk Character. Remove all detected junk characters to ensure a smooth execution of the desired actions and to preemptively address any potential issues that may arise 
Step 4: Perform a reindexing from BUSY on the database to fix any potential corruption issues that might be causing the lock file error. To do this, go to the Company →Reindex Database.
Step 5: If the issue remains unresolved even after reindexing data, this data needs to be review by our support technical team so 
 share the backup data with us on support@busy.in.
