Obtaining Min and Max Dates from month and year listboxes

[Anonymous]

Morning guys

If I have two list boxes, one each for "Year" and "Month", how would I write an expression that would return either the min or max dates of my selection combination.

I.e if I have 2016, and January selected, how would I return 01/01/2016 and 31/01/2016?

Many thanks,

Gareth

then use below, in two variable

MinVariable

=monthstart(floor(date#(max(Year)&max(Month),'YYYYMMM')))

MaxVariable

=monthend(floor(date#(max(Year)&max(Month),'YYYYMMM')))

Sorry to be a pain, but how would I write an expression using these to count the dates in a field that fall between the range specified (using these two expressions)?
