Excel Tips: Using Indirect References
If, in Excel, you create a link to a cell, eg =F3, then insert a column before column F, your formula will automatically change to =G3. This occurs even when you use absolute references like =$F$3. To prevent this change, use the INDIRECT function. For example, if you wanted to sum part of a row of cells, instead of using =SUM(F6:Z6) you would use =SUM(INDIRECT("F6:Z6")) Now if you insert a new column the formula will still refer to the original values.
