I am having a problem with a fill issue. On a 'Calendar' tab I am trying to fill cells E3 through to AI3. Cell E3 states ='Holiday Leave'!B5, Cell E4 states ='Holiday Leave'!B6. I need this to continue with B7, B8, B9 etc. When I use the fill option it continues a sequence using the Letter instead of the Number. Is there an easy fix for this as in changing the fill option or do I need to insert a formula. I have came across this problem several times and have never worked it out.
