BIRT - How to insert different data set rows in different places in a single text element - birt

Question

I'm developing a BIRT report and this is my situation.
I have one text element, let's say this:
blue square: 111
blue triangle: 222
red circle: 333
At the moment is static, and always displays the numbers you see. I would like to make the numbers dynamic so I created a SQL query and I have embedded it in a dataset. Let's say this is the output:
color shape count
blue square 123
red circle 456
blue triangle 789
I would like to set it up in such a way that each data set row matches the correct row in the text file, so it would become:
blue square: 123
blue triangle: 456
red circle: 789
And will be automatically updated.
I've binded the text element with the dataset and wrote this as a test:
blue square: <VALUE-OF>if (row["color"].toUpperCase() == "BLUE") { row["count"] }</VALUE-OF>
blue triangle: 222
red circle: 333
But when I run the report it doesn't work and the value is blank.
What am I doing wrong?
Thank you all for the help and let me know if you need more info.

You now have a dataset with row[color], row[shape], row[count] to simplify your desired output I would add a "computed column" to your dataset.
e.g. row[output] = row[color] + ' ' + row[shape] + ': ' row[count]
Once you added the computed column just drag and drop your dataset into your report (where you now have the text element) and delete the unused columns.
Tip: if don't know "computed columns":
  use Google image search for "bird computed column example"
  the Google text search might get you lost in birt forum lists.
Update:
It’s possible you have some typo in your scriptlet. In BIRT a scriptlet resolves to the last expression within itself.
Your scrptlet <VALUE-OF>if (foo) { bar }</VALUE-OF> doesn’t have a last expression. (It's not wrong but BIRT may not "understand" it this way) Try instead <VALUE-OF>var result = ''; if (foo) { result = bar }; result;</VALUE-OF> and format the scriptlet to several code lines with result; as last line. This is the same as if we consider the scriptlet as a function in some programming language and the last line of the function would be return result.
