USERFORM PRINT BUTTON

Can someone help me figuire this out. I made a user form that pops up when you select the print button. On the form you select the checkboxes for each page you want to print(all pages are on the same sheet) I then use the code below to transfer the range for each page, to the sheet. I then concatenate all the ranges together to get one combined range.
what I need is to be able to press the CommandButton labeled print on the user form and have it print the concatenated range( this is located in cell "I102" on sheet4 and may look something like this) "A1:Y35,BV2:CY35"

thanks steve
