How to sort values in a column if values are time

[#1]

I have a table with these columns:

Date (mm/dd/yyyy)

Time (hh:mm:ss)

Queue (plain text)

Count (integer)

I am trying to sort the table by time. Also, i need to retrieve the earliest time where the count != 0, among other things. IS there an expression that I can use in order to retrieve this information. I would try to display this in a table box or any other apporpriate sheet object. Did I mention that I am a beginner at Qlikview as I just started using this about 3 days ago? I have tried expressions like if((Queue), if(Count>0, Time = Min(Time))) and other related expressions.

Any help or ideas would be appreciated.

Hi,

To pull the lowest Time value where the Count field is larger than 0, you could use the following expression:

=minstring({$<Count={">0"}>} Time)

Please, can you explain what the statement means? I am not exactly sure what it is saying. Also, I am just looking to pull the very first time in the table the table where the count is greater than 0. Is there some kind of looping function in Qlikview so I could loop thru the times until I find the very first time that fits the criteria? Thanks.
