Cell formating based on other cell value google sheets - regex

Question

I have 2 sheets the first one is Orders and second one is the ShippingDoc.
At Shipping doc, I have Cell C2. In that cell I choose/write ID from range of A7:A from Orders.
Is there a way if I choose example ID 1 at C2 then automatically A7 at Orders to change background to green. Also if I change the ID to 2 the A8 to be green and to not delete the A7 color.

Answer 1

There is a better way of achieving this using Apps Script. Go to tools->Script editor and there use the following code (explained on the comments in the code):
// Update everytime the value on C2 changes
function onEdit() {
var spreadsheet = SpreadsheetApp.getActive();
// Get C2 value
var C2value = spreadsheet.getSheetByName("ShippingDoc").getRange('C2').getValue();
// If input value is higher than 0
if(C2value>0){
// Ofset to set the background after A7
var number = C2value+6;
// Set background color of appropiate cell
spreadsheet.getSheetByName("Orders").getRange('A'+number+'').setBackground('green');
}
}

try:
=(REGEXMATCH(""&INDIRECT("ShippingDoc!C2"), ""&A1))*(A1<>"")
