Can multiple IIF statements in a form significantly slow the form down?

Thanks

Thanks Carlos. I ask as I have a database split into fe/be and I found that the forms on the front end with the IIF statements were very slow, but when they were taken out the form was much faster, also during the pause the form says "calculating..." in the status bar.

Would IIF statements on a form cause a slowdown effect in such a case where they look up information in a back end database of roughly 5Mb)?

Thanks again

Access tip:

Choosing data types in Access

Not sure which data type to use for your Access fields? Here are some guidelines to help you choose a data type to assign to a field.

- The Text data type can accept up to 255 characters. For information that will be recorded in paragraphs, use Memo.

- Also use Text for numbers that aren't going to be used in calculations, e.g. phone numbers.

- Use the Currency data type for monetary amounts.

- Use Date/Time for dates.

- Most other numbers can use the Number data type, but the Field Size property may have to be altered.

- For fields that have only two alternatives (yes, no) use Yes/No data type. If there is likely to be a third entry option (e.g. maybe or don't know) use Text instead.
