Macro User Input

Hi guys,

I would like to do a Macro which requires user to go to a specific line which is variable in each work sheet. I would like to be able to enter the number and then delete all lines below that point and then continue with the balance of the macro.

Is there an easy way to pause the Macro and then restart it? Or is there a code that I can insert in the Macro to locate a specific Cell and then delete all lines below the next line?
