Hi @Chanel_C2019 - if I understand correctly, what I think you need is this:
Rather than saying:
“If UTM content is empty, let the result be empty, otherwise…”
I would switch this around and say:
“IF UTM Content exists, then…, otherwise”
So in my example above, the formula field is:
IF(
{UTM Content},
IF(
FIND('?', {Link To}),
{Link To} & 'string' & {UTM Content},
{Link To} & 'string2' & {UTM Content}
)
)
As it stands the results look a bit strange, as I don’t know what “string” and “string2” should be, but hopefully this will give you enough to edit as you need.
