SID-01637: Display icon based on a condition

I tried using the following statement inside a cell of a table

%IF{"istopic 'Sandbox.TestTopic'" then="%Y%" else="%X%"}%

All I am getting is something like "<img src=" in the cell, irrespective of whether the topic exists or not. Please help me with this.

Discussion and Answer

This is because variables resolve inside out, e.g. %Y% expands and contains double quotes, which terminates the IF prematurely. Either use single quotes for IF, or escape the variables, such as then="$percntY$percnt". Details in IfStatements and VarIF.
