count if with multiple criteria

[#1]

Hi. I've been googling and looking around here for some help with count if statements within Qlikview.

So far I've managed to use

count({< TalkTime = {'>=180,<240'} >}  distinct(callerID) )

However, the numbers just don't seem to be correct. I have in my database hundreds of call records and want to count those less than 3 minutes, 3-4 minutes etc. The one above should count just those calls which are 3-4 minutes in length.

Is this correct?

Many thanks

Test:
{">=180<240"}

Without comma and using double quota
