Formatted as number

I have a unique ID which is the combination of three fields of text which works fine. At the end though I have it append a number field then / then another number field. It gets me to format the number as, where I select no decimals. It works however instead of getting 1/1 as expected I am getting 1 / 1 which isnt what I want. How do I get rid of the spaces? keeping in mind there are spaces elsewhere in the text I want to keep.

Can you show the expression?

sounds like arbitrary text may be what you want to use to create your text

All good I worked out what I was doing wrong. I had entered the spaces in the field it was referring to myself. Took them out problem solved Thanks
