Changing row colours in SSRS based on values in a specific column in that row

Hi Guys,

I'm working on a table report in SQL Server Reporting Services.

I've managed to get all the values in the table that I want, but now I want to tell the table that I want a row to be grey if one of the values in that row is below a specific threshold, and otherwise to just alternate between two other colours.

I've managed to get the alternating colour going with:

=IIF(RowNumber(Nothing) MOD 2,"#f6e1e1","#f7cfcf")

However, I can't figure out how to add the clause for the grey in to that as I've tried a couple of alternatives involve orelse after the grey value etc etc. but just keep getting errors.

I'm still learning SQL atm but some guidance would be really appreciated.

Cheers

Rachel
