Function if
If testCondition evaluates to 0 then the result of falseExpr is returned, otherwise the result of trueExpr is returned. Note: both trueExpr and falseExpr are evaluated no matter what the result of testCondition is. You may want to consider using [if():] instead.
Test condition notation: > for great than < for less than >= for greater than or equal to <= for less than or equal to == for equal to - yes, you must use TWO equal signs when setting the condition. If you are checking for a text string, place quotes around the text.
Usage
[h: result = if(testCondition, trueExpr, falseCondition)]
Examples
[r: if(a>b, "A is larger than B", "A is not larger than B")]
[someProperty = if(variable>=1,20,"")]Sets someProperty to 20 if variable is greater than or equal to 1, or makes it blank (but not empty) otherwise.
[someProperty = if(variable=="Text",1,0)]Sets someProperty to 1 if variable contains the text string Text, 0 otherwise.
