Macro to print multiple sheets

I have a spreadsheet set up with multiple worksheets. I have one worksheet (Form tab) created that will pull data from the other sheets that I want to print. Have macros set up to gather sheets which put the sheet names in a combobox and to printform. Can't get the print feature to work correctly. It only prints the sheet that's selected but it's not cycling properly. Any assistance someone can provide will be greatly appreciated. Not sure what's going wrong. Same code I use every year.
