Simple Reset and activate a cell for the next input

[AV TL]

This might be an extremely simple question:  After I click on Reset Button, I activate cell C5.

When I try to scan the next item, my button get activated.

function reset_barcode() {

 

//clears barcode which was scanned

var pricesheet=SpreadsheetApp.getActiveSpreadsheet();

var priceform=pricesheet.getSheetByName("FORM");

var D_Range=priceform.getRange("C5");

priceform.getRange("C5").clear({contentsOnly: true, skipFilteredRows: true}); //Clears barcode in C5

priceform.getRange("C5").setBackground('#00DFFF');

priceform.setActiveSelection(D_Range);

return true;

}
