Hi there, posted this in the sforce community boards but then thought it might be a more 'techie' question that someone might have seen before... grateful for any feedback.

Hi there, not sure if anyone has run into this one. I have been doing some work on my developer instance (na3) to create a formula.

if( Forecast_Period__c = "90", case( Probability , 1, 1, 0.9, 1, 0.8, 0.9, 0.7, 0.8, 0.6, 0.7, 0.5, 0.6, 0.4, 0.5, 0.3, 0.4, 0.2, 0.3, 0.1, 0.3, 0, 0, 0), if( Forecast_Period__c = "60", case( Probability , 1, 1, 0.9, 0.9, 0.8, 0.8, 0.7, 0.7, 0.6, 0.6, 0.5, 0.5, 0.4, 0.4, 0.3, 0.3, 0.2, 0.2, 0.1, 0.1, 0, 0, 0), if( Forecast_Period__c = "30", case( Probability , 1, 1, 0.9, 0.9, 0.8, 0.7, 0.7, 0.5, 0.6, 0.3, 0.5, 0.1, 0.4, 0.1, 0.3, 0.1, 0.2, 0, 0.1, 0, 0, 0, 0), 1)) )

This compiles to 1,597 chars, which works fine as it's under the 4k limit. However I then cut and paste to my client's SF instance (emea) and the exact same formula, exact same field names, compile to 18,197 characters! I have re-compiled the formula in the developer instance and it's still fine, so not sure what would be causing this one. It's really driving my nuts as everything else - field names, numbers, the browser, it's all the same!

Anyone else come across this seemingly bizarre issue?

Thanks,
Stephen
