Out of memory problem

[#1]

I'm very new to this Qlikview program and I have questions as follows;

1.I'm trying to create a pivot chart but It always not responding and display 'Out of memory'.

How can I fix this problem?   My data source is SQL.

2. I want to create a listbox which i can click on it to choose which month to show the data just like below

Jan	Feb	March	Apr	May	June	July	Aug	Sep	Oct	Nov	Dec

What  is the expression do I have to type?
