Clear values, save formulas; Recalculate

The attached sheet is used to inventory lottery tickets. The ticket number is scanned with a barcode reader and the info placed on an input line. Several other details are added then the line is "Added to inventory" with the macro button. The macro clears the input line so the next item can be entered. I can't clear the values without dumping the formulas in the calculating cells, which wouldn't be an issue but the cells won't recalculate the new input.

I need to be able to clear the cell values (but leave the formulas) and need to kick the sheet to recalc the input row. Ideas?
