FIND & REPLACE Airtable Advance Search within Zapier

Hi
I am trying to create a formula to do a find on two fields and if they are an exact match replace the third field content with a new URL in my ZAP (Zapier).

The very first field is being used as a UID:
– RECORD_ID() Airtable formula named “Handle”
&
– Text field named “Variant_SKU”
IF they match Replace
– Text field content named “Image Hi Src”

I hope this makes sense, thanks in advance for your help.
