Thank you very much Mike.
What i meant was:

week 16, week 26, week 30 is the string of a multiple selection.
So my purpose is to sum the sales of weeks 16,26 and 30.
I use this *"..If InStr( i1, i2 ) 0 Then.." and week 1 joins the
club.

Thank you.

Rumkus,

You could either add another integer digit to your "week" name for
single digits, e.g. week05 instead of week5, and use StrComp (see
"TestStrComp" below), or you could parse off the number and do a
number comparison (see "TestParse" below and read the commented
assumption).

Best,

Debug.Print "strTwo:"; strTwo; " | strOne:"; varSplit(intI)
