dsum search criteria (quicker way?)

[mxp]

i am just starting to use dsum to do some simple calculations and i want to calcualte the sum of several columns.

usually i write by search criteria like this

search_criteria 
="=1"  

but if say i'd got 100 values to serach by how could i achieve the following without manually writing each one out?

="=1" 
="=2" 
="=3"  

many thanks

to answer my own question

i had assumed that the formula needed to be in the format

="=1" when in fact because its an integer and not a string it can simply be in the format =1, which obviously is easy to drag and copy up to any value.

many thanks
