Describe the bug
Some validation is missing in the action "Continuer seulement si", as it's possible to enter a value such as ",15" in the field that should only accept a numeric value.
Here is a screenshot :

Then, when a scene with such value is executed by Glayds, the following error occured :
<warn> scene.executeActions.js:37 (executeAction) SyntaxError: Value expected (char 1) at createSyntaxError (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1623:17) at parseEnd (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1590:13) at parseParentheses (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1577:12) at parseNumber (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1550:12) at parseObject (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1534:12) at parseMatrix (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1466:12) at parseSingleQuotesString (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1382:12) at parseDoubleQuotesString (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1338:12) at parseSymbol (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1237:12) at parseCustomNodes (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1210:12) at parseLeftHandOperators (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1134:12) at parsePow (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1116:12) at parseUnary (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1105:12) at parsePercentage (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1065:12) at parseRule2 (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:1016:16) at parseImplicitMultiplication (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:988:12) at parseMultiplyDivide (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:958:12) at parseAddSubtract (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:931:12) at parseRange (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:893:14) at parseConversion (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:858:12) at parseShift (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:835:12) at parseRelational (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:797:19) at parseBitwiseAnd (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:783:16) at parseBitwiseXor (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:768:16) at parseBitwiseOr (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:753:16) at parseLogicalAnd (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:738:16) at parseLogicalXor (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:723:16) at parseLogicalOr (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:708:16) at parseConditional (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:679:16) at parseAssignment (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:632:16) at parseBlock (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:580:14) at parseStart (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:551:16) at string (/src/server/node_modules/mathjs/lib/cjs/expression/parse.js:75:14) at parse (/src/server/node_modules/typed-function/lib/esm/typed-function.mjs:1790:20) at string (/src/server/node_modules/mathjs/lib/cjs/expression/function/evaluate.js:50:14) at evaluate (/src/server/node_modules/typed-function/lib/esm/typed-function.mjs:1790:20) at /src/server/lib/scene/scene.actions.js:264:17 at Array.forEach (<anonymous>) at Object.condition.only-continue-if (/src/server/lib/scene/scene.actions.js:261:23) at executeAction (/src/server/lib/scene/scene.executeActions.js:32:35) at /src/server/lib/scene/scene.executeActions.js:66:13 at tryCatcher (/src/server/node_modules/bluebird/js/release/util.js:16:23) at MappingPromiseArray._promiseFulfilled (/src/server/node_modules/bluebird/js/release/map.js:68:38) at MappingPromiseArray.PromiseArray._iterate (/src/server/node_modules/bluebird/js/release/promise_array.js:115:31) at MappingPromiseArray.init (/src/server/node_modules/bluebird/js/release/promise_array.js:79:10) at MappingPromiseArray._asyncInit (/src/server/node_modules/bluebird/js/release/map.js:37:10) at _drainQueueStep (/src/server/node_modules/bluebird/js/release/async.js:97:12) at _drainQueue (/src/server/node_modules/bluebird/js/release/async.js:86:9) at Async._drainQueues (/src/server/node_modules/bluebird/js/release/async.js:102:5) at Immediate.Async.drainQueues (/src/server/node_modules/bluebird/js/release/async.js:15:14) at processImmediate (node:internal/timers:476:21) { char: 1 }
