Referencing a cell from another sheet

Referencing a cell from another sheet

My workbook has multiple sheets. Each sheet has some calcluated totals in certain cells. The front master sheet has a list of everything that is detailed on the other sheets, with the totals. These could change at any time, so the totals need to be references to the other cell's value, not a fixed number.

So on the master sheet, I put in =, then go the other sheet and choose the cell and hit Enter. In regular Excel, this works. But in the Zoho sheet, it doesn't work. I have to edit the result by adding apostrophes before and after the sheet number to make it work. How can I do this without the manual edit?
