Invalid Number Error in fetching Basic Salary Component

Summary:

We are writing an oracle sql query to fetch different components in the salary for inactive employees. But it keeps showing below error on runtime.

ORA-01722: invalid number

Content (required):

FGBF.GLOBAL_VALUE and PEVF.SCREEN_ENTRY_VALUE both are character value so we are trying to convert it to Integer value so multiplication/division can be used on it. But the sql query is giving Invalid Number error.
