Thanks

[@excel-k-sir]

Hello Dhruvin, While creating the global variable you ended it semi column(;) but when you defined the global variable on startup you never used the semi column.
Please help

[@iamdhruvinshah]

If you want to add second formula after set use ;
Otherwise you can keep as is
Hope it's clear

[@chennakeshavanaidunallapat27]

Can we change the value for Set Variables in another screens

[@iamdhruvinshah]

Yes

[@iamdhruvinshah]

Yes

[@nikhil_joy]

glbFontSize is not getting set. In variables, it is showing as 'No value'.

[@udaykiran-mw5yn]

if you set this variable in button onSelect, you to click on button to initialize the value
By default there won't be any value for any variable
