Unidentified error with certain cells values causing #value! error with MATCH formula

Question

Can you please assist me in trying to identify what is wrong with certains values causing a formula that works fine on the vast majority of cells to returns a #value! error?

=MATCH(LEFT([@ID],FIND("~",[@ID])-1) & "|" &[@Original],V1_TTK_strings[Real ID],0)

Example of value where the formula fails:

While the internet undoubtedly presents fantastic opportunities for children, it is equally clear that there is a real opportunity for children to be put at risk by their exposure to material and/or individuals which may be harmful. 

Answer 1

MATCH can only handle texts up to 255 characters. As your texts are longer, you do not get a hit.

Instead, use this formula:

=MATCH(TRUE,(LEFT([@ID],FIND("~",[@ID])-1)&"|"&[@Original])=V1_TTK_strings[Real ID],0)

You need to enter it as an array formula, ie press Ctrl - Shift - Enter .
