Retrieve input values from the selection screen

I have a requirement to retrieve the variable value or values inputed from the selection screen and label the worksheet tab to replace the tab name 'Sheet1' from the Excel. The only way to do this would be to write a macro to label the sheets but how would I retrieve the value(s) from the selection screen criteria? Is the value of the selection screen entered by the user stored in some table? How would I write the macro to retrieve this value?

For example, I want to retrieve the company code entered from the selection screen and lets say the company code entered as 10; I would want to replace the worksheet from 'Sheet1' to '10' . Texts would be more recognizable.
