Looks like you are missing one closing parenthesis at the very end. You have 4 IF( statements, but only 3 of them are closed. That should be all – assuming your quotes are “straight” quotes in the Formula editor.

IF(

SEARCH(“1”, {Type of Workshop or Class Offered}),

DATEADD({Proposed Date of Workshop or Class}, 0, ‘days’),

IF(

SEARCH(“2”, {Type of Workshop or Class Offered}),

DATEADD({Proposed Date of Workshop or Class}, 1, ‘days’),

IF(

SEARCH(“3”, {Type of Workshop or Class Offered}),

DATEADD({Proposed Date of Workshop or Class}, 2, 'days’),

IF(

SEARCH(“4", {Type of Workshop or Class Offered}),

DATEADD({Proposed Date of Workshop or Class}, 3, 'days’)

)

)

)

)

So this should work?

Yep - that looks valid to me.

would it matter if some is nested and some is not?

what key strokes are used for nesting spacebars or tab?

Nesting should not matter - the formula editor ignores most whitespace.

Are you still getting errors? If so, the next thing to check would be the quotation marks. If you are copy-pasting what is here in your forum posts, you are going to end up pasting “smart” or “curly” quotes – they all need to be replaced with " and ' - “straight” quotes.

It was the straight quotes! Good call!

For the benefit of future forum readers, could you mark my original reply as the “Solution” here – that was the primary issue with your formula at first.
