Hi

I am having trouble summing a range of cells that meet multiple criteria.

I have 3 resources clin040, clin060 and clinmix. These resource codes appear
in column K. Column K also contains many other resource codes. I need to sum
all the cells in column AL that have either clin040, clin60 or clinmix in
column K.

I also need to do this over a number of sheets - clin1, clin2 clin3 etc to
clinEND, and have a total of all cells with those resources across all the
sheets.

Please help!
