VBA to print based on cell value

Hi

I want to print X copies of worksheet 1 based on a qty in a cell C3

Then to Print X copies of worksheet 2 based on cell C4

But if cell C3 is blank i still want to print worksheet 2

but when i run the macro i get a error because there is no value in C3

Can anyone advise me on how to get the macro to continue if C3 is blank?

Thank you any help / advice you can give

Please note macro im using on Sheet 3 of the attachment
