So you’ve made a string table, gathered, translated, and compiled your text, and are now trying to find the text from the string table using the “Find Text in Localization Table” node?
Finding text in this way isn’t really recommended as it can be very fragile unless you’re meticulous at naming things. We also have the “Make Text from String Table” node which takes the string string table name (which is the asset path if you’re using an asset) and the key, although this is also not generally recommended, as linking a “Make Literal Text” node to a string table entry is much more robust.
Could you include a screenshot of your string table, and also the BP that’s trying to access the text?
