https://community.blueprism.com/t5/Product-Forum/Syntax-Error-Invalid-token-Commas-being-interpreted-as-decimals/m-p/75547#M28152 Hi,   I have experienced this exact issue and the advice above is correct.  You need to change your number formats in the local regional settings to use "." as decimal and not ",".

It seems to be interpreting the 8 and 3 as decimals. Please see the attached picture.  Tue, 30 Apr 2019 14:49:00 GMT https://community.blueprism.com/t5/Product-Forum/Syntax-Error-Invalid-token-Commas-being-interpreted-as-decimals/m-p/75545#M28150 MotheoMotlhaba2 2019-04-30T14:49:00Z https://community.blueprism.com/t5/Product-Forum/Syntax-Error-Invalid-token-Commas-being-interpreted-as-decimals/m-p/75546#M28151 This sounds like something to do with the locale setting of the PC where commas denote a decimal point. Maybe try experimenting with an English setting?
