Word count in a field

[Duleepnagahawatte]

I need to find how many times a particular word appears in a particular field.

How can i do that?

for an instance - (jan,mar,jan,feb,aug,sep,jan)

how many "Jan"'s in the above field?

You could use Split to get each element into an array and then loop through them.

[Crystal Fire]

Put the field in the detail secton and either use the sum tab and use the DistinctCount option or write a a formula
"DistinctCount (your field)"

[JaganEllis]

It looks like Crystal Fire and I have understood your question differently.
Do you have a field which contains the string "(jan,mar,jan,feb,aug,sep,jan)" and you want to know how many times Jan appears in it, or do you have a field containing one month name and you want to know how many times each month name appears in the report?
