I am using PhpExcel 1.8.0 and I have faced with the problem. PhpExcel can't calculate formula OFFSET() with 4 arguments:
"Price Sheet!A27 -> Program Settings!H2 -> Formula Error: Wrong number of arguments for OFFSET() function: 4 given, either 3 or 5 expected"
But in description of this formula i have found that this argument "width" is optional:
"It is the number of columns that you want the returned range to be. If this parameter is omitted, it is assumed to be the width of range."
Can someone tell me how to fix this problem?
