Dear all, i admit im going nuts.
I have a simple gallery, pulling info from a sharepoint list. Simple and working ok.
Now the issue starts when i wanna search the data from the sharepoint list.
On a break down, the fields i have are:

All of them are text, except:
IDLists - number
MaxPriority - number
ModifiedBy - user
UpdatedOn - date
This is my search options:

Meaning, i want the search to be made in 1 of 2 ways, either by App, or globally (all records)
The issue starts when i wanna search the info on the sharepoint.
My actual code is:
Filter(EditableEC,((If(Checkbox1_3.Value=true ,Find(Trim(Upper(TextInput1_1.Text)),Trim(Upper(AssignmentGroup)))) > 0)))
And this is only part of the search i need to make, but already gives me this feedback:
Can anyone please help? 😞
