Updating Custom Metafields : adding values

[Cleronhigh]

So i created a workflow where i want a custom integer customer metafield to update its value by 1 (or whatever number) 

however i cant seem to make it work. if i put something like {{ 1 | plus: 1}} it ofcourse always will set the values to two. something like {{ value | plus: 1 }} returns an error. is there something obvious i am missing ? any help would be appreciated

Start by sharing the error that you are getting. Do watch out for excess white space by using hyphens like 

{{- foo -}}

For accessing the current value, click "add a variable", and choose order / customer / metafield. Then choose the metafield to set up an "alias". Docs are here on this new feature: https://help.shopify.com/en/manual/shopify-flow/reference/metafields#get-metafield-data

Thanks for the quick help, i did it like this now, the workflow suceeds but the value doesnt actually change.

Your namespace is likely not customer but custom or something else.

that was it, seem to have changed it to test something but forgot to change it back, thanks for the super quick help!
