The formula in Excel is this,
=FUT_CHAIN!$D$9-LME!$F$2
Each time I click the VBA, it should shift one column in the formula but only limited to the first component, which means that the formula would be,
=FUT_CHAIN!$D$10-LME!$F$2
The $ inside the formula and the second component can not be changed or eliminated.
